Question

An ice skater skates completely around the two circles shown in the picture. Each circle has a diameter of 20meter. What is the approximate total distance skates by the ice skater? A. 126 B. 251 C. 628 D. 63 don’t have much time

Answer 1

as the radius is the same for both circles. We get that

`d=2\cdot2\cdot\pi\cdot r=4\cdot\pi\cdot10=40\cdot\pi\approx126`

so the answer is A
