Learn how to identify the diameter and circumference of a circle. Then, collect data on a circle and relate it to the diameter and circumference of a circle. Last, plot data and find the line of best fit.

How do you find arc lengths and areas of sectors of circles? Young mathematicians investigate the relationship between the radius, central angle, and length of intercepted arc. They then learn how to determine the area of sectors of...

Invite your learners to take a closer look at the art and mathematical function of dome buildings as designed by the ancient Romans. In the next segment of this attractive worksheet set, your young historians will then learn about...

Introduce learners to two methods to estimate the formula for the area of a circle. The first method uses a sector of a circle to form a rectangle, and the other uses grids to estimate the area. The problems in the 18th segment of a...

Students explore circles. In this algebra/geometry lesson plan, students discover the formula for the area of a circle, as they investigate the ratio of the area of a circle to the radius^2.

Students analyze and demonstrate how a circle can be measured in square units and examine how diameter, circumference and radius are related.

Sixth graders measure circumference and diameter to the nearest eighth of an inch, record measurements on a spreadsheet, and use the internet to complete a "scavenger hunt" of facts concerning pi.

In this geometry worksheet, students calculate the radius and the diameter of the five given circles. There is an answer key included.

For this circles worksheet, students use given radius or diameter measurements and find the circumference and area of circles to one decimal place.

Students understand where the number for pi comes from. They understand and use the formula for circumference. Students measure the circles given out and the diameters of those circles and record the results on their worksheet.
