Question

The circumference of a circle is 125.6 millimeters. What is the circle's diameter?

Use 3.14 for ​.

Answer 1

C = 2 pi r, so diameter is 40!

Explanation

125.6 = 2 pi r

125.6 divided by 2 is 62.8.

Now its, 62.8 = pi times r

62.8/3.14 = 20.

r = 20

but this is the radius so the diameter is 2 times for than the radius. 20 x 2 = 40

Answer 2

The answer to your question is 40
