Question

The concentric circles on an archery target are 6 inches apart. The inner circle (red) has perimeter of 37.7 in. What is the perimeter of the next-largest (yellow) circle?

Answer 1

Find the radius of the inner circle.

Answer 2

Can you do that?

Answer 3

no :/ idk how to do it

Answer 4

The circumference formula is C = 2pi(r) Replace C with 37.7 and solve for r

Answer 5

ok r=6.0 what next?

Answer 6

The problem says that the circles are 6 inches apart so the next bigger circle must have a radius of 12. Would you agree?

Answer 7

so then the final answer would be 75.4?

Answer 8

Good job!!

Answer 9

cool thanks
