Review Graphing Parabolas & Circles
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.
The Moon's Density-What's Inside?
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.
Tidal Forces-Let'er Rip!
In this tidal forces learning exercise, students 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.
Measuring the Speed of a Solar Tsunami!
In this solar tsunami worksheet, 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.
Arclength and Trigonometric Graphs
Students calculate the third quantities. In this trigonometric lesson,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.
Coordinate Geometry - Circles
Students construct circles using Cabri Jr. In this circle construction using Cabri Jr. lesson, students construct a circle using Cabri Jr. Students measure the diameter and radius. Students find points on the circle in order to find an equation to model their circle. Students move their circle and discuss the differences in the equation.
Finding Mass in the Cosmos
In this finding mass in the cosmos worksheet, students 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.
How To Build a Planet From The Inside Out!
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.
Fuel Level in a Spherical Tank
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.
What do Atoms Look Like?
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.
Planet Earth in Cross Section
Students will examine the layers of the Earth. In this geology lesson, students create a scale model of the Earth's interior using cash register tape. They will determine the percentage of error in the scale compared to the actual size of the earth's radius.
Definitions of Parabolas
In this algebra worksheet, 11th graders identify parts of a parabola and circle. They solve systems of equations and answer questions about radius, foci and conics. There are 20 questions on this test.
The Cylinder Problem
In this calculus lesson, learners build a family of cylinders and explore the relationship between the dimensions of the generating rectangle and the resulting cylinders. They write the volumes of cylinders as a function of the radius and use derivatives to find the cylinder with the greatest volume, given a fixed perimeter.
Calculate the Radius
For this finding the radius worksheet, learners calculate the radius using the given area of 5 circles. They use the blank boxes to show their work and write their answers to the nearest tenth.
in this radius worksheet, students calculate radius from given circumference of circles and round answers to the nearest 10th. An answer key is provided.
In this geometry worksheet, students calculate the radius and the diameter of the five given circles. There is an answer key included.
Calculate the Radius
In this radius worksheet, students calculate the radius of a circle when the area is given to them. Students complete 5 problems total.
Calculate Radius and Diameter
For this radius/diameter worksheet, students calculate radius and diameter from areas given. Workspace is given for each problem.
How Do You Find the Radius of a Circle if You Know the Area?
Given the area of a circle and a formula, is it possible to find the radius of the circle? Of course it's possible! Use the formula for the area of a circle, plug in the known values and do the math. The solution has been found.
Circles Notes: Diameter, Radius, Circumference, and Area
A note-taking sheet and homework are paired up in this resource. Through both, your class will learn the definitions for the diameter, radius, area, and circumference of a circle. The notes guide also displays the formulas for computing the area and circumference. Work a few examples with your class, and then assign the rest as homework. A neat and user-friendly document!
