In this length of the arc worksheet, students are given the measurements of the radius and central angle and they find the length of the arc. Students complete 6 problems.
Sixth graders explore geometry by analyzing specific shapes in class. For this circle identification lesson, 6th graders utilize a computer and projector to view the different measurements of a circle. Students define the terms radius, diameter and circumference in order to find the area of any given circle.
In this circles worksheet, students label parts of a circle that are given. They choose from center, radius, diameter or chord. Students then draw a circle and draw the given parts on their circle. The worksheet ends with a test prep section where they are given a multiple choice question and a story problem.
Students work with circles, angles and estimating angles in the night sky. In this circles and angles lesson, students practice measuring a degree using the circumference of a circle and apply the degree to determine a way to use their hands take measurements. They determine the angular size of the moon, planet or a star using the given algorithm.
In this math word problem worksheet, 6th graders complete problems about the length and radius of certain shapes. Students complete 15 problems.
In this arcs and chords worksheet, 10th graders solve 7 different types of problems related to identifying arcs and chords in a circle. First, they find the measure of each arc to the nearest tenth, if O is the center point. Then, students find the length of a radius in a circle where the chord is 16 inches long and 6 inches from the center. They also find the distance from the center of the circle to the chord.
In this solids activity, 10th graders solve and complete 10 different word problems that include determining the volume and surface area of various solids. First, they determine the surface area of a cube as described. Then, students determine the radius of an object given the diameter and length. In addition, they determine the amount of a substance held in a cylindrical glass,
In this circles worksheet, 10th graders solve and complete 5 different problems related to measuring circles. First, they find the length of a given line when it is tangent to the circle with a given radius. Then, students write a two-column proof given the information. In addition, they determine the radius of each circle given the measure of each line segment.
In this circumference of a circle worksheet, students complete 5 problems showing their understanding of circumference, diameter and radius. Students prove their understanding by showing their work and explaining their thinking.
In this circumference worksheet, 6th graders read the steps to find the circumference of a circle using radius and diameter. They solve six problems.
Learners study the properties of circles. In this circles lesson, students read a word problem about circles. Learners watch a video about the activity and then practice drawing the circle solution to the problem. Students watch another video segment and discuss the methods in the video. Learners identify circles around the classroom and find their centers and radii. Students finish with two assessments for the topic.
As a sample exam, or exam itself, this might save you some time. However, you will need to review the questions to see if they are all topics covered in your chemistry class. Topics included are electron configuration, Pauli Exclusion Principle, atomic and ionic radii, ionization energy, electron affinity, and trends in the periodic table of elements.
In this chain rule and directional derivatives instructional activity, students solve 4 different word problems related to determining points. First, they find the rate at which a trees volume grows per year when its radius is a particular number and its height is a certain number. Then, students find the directional derivative of a function at a point in the direction of the vector. In addition, they find the directions of the steepest slope and the magnitude of the slope in that direction.
In this circles worksheet, 10th graders solve and complete 10 different problems that include various parts of a circle. First, they write the name of the designated coordinates in each. Then, students determine the diameter, chord, center, and radius in each using the given information.
For this geometry worksheet, students focus on the parts of a circle. Students solve for 8 problems, and decide if what is shown depicts a radius, diameter or a chord.
In this circumference of a circle worksheet, students discuss the definition of a radius and diameter of a circle. Students then complete 6 problems where they decided if the marked part of a circle is a radius, diameter or neither.
High schoolers explore the concept of surface area.  In this surface area lesson, students find the surface area of a cylinder.  High schoolers use Cabri Jr. to make a chart of circle radius, rectangle height and length and then find the surface area of a cylinder.
Sixth graders discover what circumference is.  In this measurement instructional activity, 6th graders identify the radius and diameter of different circles. Students discover how to find the area of a circle using the radius and diameter.
For this finding the area of a circle worksheet, 7th graders read the formula, then calculate the area for 5 circles, given the radius, with answers included.
In this geometry worksheet, students calculate the circumference of a circle. They calculate the diameter and radius using the correct formula. There are 5 questions with an answer key.
