Question

The circles are identical. Find the circumference of each circle. Round your answer to the nearest tenth.

Answer 1

62.8

Explanation:

The diameter of the first circle is 10x since the diameter is twice the radius.

This means that since the circles are identical, 10x=6x+8, and thus x=2.

This means the diameter is 20, and thus the circumference is

`20\pi \approx 62.8`
