What is the radius of a 5.25 inch circumference circle?

To find the radius of a circle given its circumference, you can use the formula ( C = 2\pi r ), where ( C ) is the circumference and ( r ) is the radius. Rearranging the formula to solve for the radius gives ( r = \frac{C}{2\pi} ). For a circumference of 5.25 inches, the radius would be ( r = \frac{5.25}{2\pi} \approx 0.84 ) inches.
