Circumference of Circles: Find Missing Radii #1

Rally to find radii in this circumference worksheet! In each of eight problems, students are asked to find the radius of a circle based on its circumference. Using the circumference formula, learners will work backwards to solve for the radius. 

Created for a seventh-grade curriculum, this geometry worksheet is a great way to practice using the circumference formula to find other circle measurements. As they work through each problem, mathematicians will better understand the relationship between the radius, diameter, and circumference of a circle.
