Tenth graders explore and define the radius and diameter of a circle. In this geometry instructional activity, 10th graders calculate the circumference and area of a circle using real world objects and shapes. They discuss chords and lines tangent to a circle as it relates to tangency.
For this Sombrero Galaxy worksheet, students observe infrared images taken by the Spitzer Infrared Telescope and the Hubble Space Telescope. They answer 9 questions about the details of the images such as the radius of the stellar component, the thickness of the dust disk and the diameter of the bright nuclear core.
In this equations of circles worksheet, students solve 4 short answer problems. Students find an equation of a circle given the center and radius.
Students investigate the area of a circles. In this algebra lesson, students investigate the quadratic equation representing a circle, find the radius and area of a circle and define the area and a quadratic function is related.
High schoolers investigate the relationship between the radius and area of circles that change size over time. They identify and interpret the puddle at a crime scene, that it is certain to be irregularly shaped and the floor would be neither smooth nor level. This raises several questions about the mathematics of true reality, as well as the physical chemistry involved.
For this volume and surface area worksheet, 10th graders solve and complete 12 different types of problems. First, they find the volume and total surface area of a given circle. Then, students find the height and radius of a cylinder illustrated. They also find the volume of the remaining solid shown.
In this black holes worksheet, students read about black holes and solve 3 problems where they calculate the Schwarschild radius of one, the number of grams/second a quasar luminosity implies for another and the number of suns per year a super massive black hole consumes at different efficiencies.
In this planet models activity, students use the radius of a given planet and its mass to answer questions using a model of a planet with a given radius. They determine the volume of the planet's inner core, the volume of its outer shell, and the total mass of the planet.
Sixth graders listen to the story of Sir Circumference and the Dragon of Pi. They measure the circumference and diameter of circular objects, record measurements in a table, and use calculators to divide the circumference by the diameter. They complete a homework assignment in which they find the radius of a pizza.
Students review how to graph parabolas. They practice graphing two different parabolas using the vertex and table method. They solve problems related to graphing circles, determining the radius and the center.
In this moon's density worksheet, students solve 4 problems about the Moon and a model planet. They find the Moon's density and they find its volume. They make a model of a planet's interior and use its mass and radius to find the density of the core and the mantle.
In this tidal forces activity, high schoolers read about the gravitational pull from the moon that causes the ocean tides. Students solve 3 problems including finding the Roche or the tidal radius for the Earth and Moon, comparing the Roche Limit of Saturn to its ring system and finding the Roche Limit for the sun.
In this solar tsunami instructional activity, students are given three images of the progress of a Morton Wave on the sun. They solve six problems using the images to find the radius of the sun's disk, the scale of the image, and the time that passed between each given image.
Students create a semiconductor chip using the magnification lens equation. In this physics instructional activity, students calculate the radius of the shape of the lens that allows the circuit diagram to be reduced to a reticle. They create the reduction photgraphically.
Students calculate the third quantities. In this trigonometric instructional activity,students are given information about the arc length and angle or radius and asked to find the radius or arc length. They use the unit circle to help find their answers.
Learners construct circles using Cabri Jr.  In this circle construction using Cabri Jr. lesson, students construct a circle using Cabri Jr.  Learners measure the diameter and radius.  Students find points on the circle in order to find an equation to model their circle.  Learners move their circle and discuss the differences in the equation.
In this finding mass in the cosmos worksheet, learners use the equations for the force of gravity, the centrifugal force pushing a planet outwards and the speed of a planet to solve 2 problems. They find the mass of primary bodies given the orbit radius, the period and the companion.
High schoolers read about the Spitzer Space Telescope and the technology used to learn about planet composition. They calculate the radius of a planet, the size of a planet, the average density of a planet and the likely core composition of a planet.
In this spherical tanks and fuel level worksheet, students are given a diagram showing the effects of gravity or acceleration on the level of fuel in a spherical tank. Students solve 3 problems including finding the general formula for the radius of a disk, finding the integral for the volume of fluid in a tank and finding the equation for the change in height of the fluid with respect to time as fluid is being withdrawn from a tank.
In this atoms worksheet, students complete 58 questions about the atomic radius of atoms, the ionization energy, the valence electrons, metals, non-metals and semi-metals and the families of elements.
