that is all the choices

Answer 1

Hi Treazure,

 

You need to consider the circumference of the circles to find the answer.

Each circle with radius 4 will have 2*pi*4 = 25.1 inches (rounded to the nearest tenth) of circumference

Heh as 360 inches of wire, so divide that by the circumference of each circle.

360/25.1 = 14.3 (rounded to the nearest tenth)

So, the answer is 14, choice A.
