Question

Pls help me I really need to pass

Answer 1

A. 31 Km

Explanation:

`circumference = 2\pi \:r`

radius equals the diameter divided by 2

`r = (d)/(2)`

In this case the diameter is 10, so the radius is 5.

finally,

`2\pi(5) = 31.415`

rounded to the nearest whole number gives us

31 Km.

Answer 2

Should be D. Please tell me if I’m wrong
