Circumference of Circles: Find Missing Diameters and Radii #1

Become a well-rounded mathematician by solving for diameter and radii measurements in this seventh-grade worksheet! Students will solve eight unique problems in which they must use the circumference formula to find a circle’s diameter or radius length. Learners will work with decimals to the thousandths throughout this practice.

This geometry activity can help students reinforce their understanding of the relationship between the radius, diameter, and circumference of a circle. By beginning with the circumference and working backwards, students will learn how each measurement relates to one another.
