Question

What is the circumstance of the circle? (3.14 for pi)

Answer 1

the answer for this question should be 131.88 because 21 is the radius and the radius is half of the diameter which is 42 because you need to multiply 21 times 2 getting an answer for the diameter but we use the formulas.

C=2 times 3.14 times 21= 131.88

C= 3.14 times 42=131.88

Explanation:

Answer 2

131.88in

Explanation:

C = 2πr

The radius of the circle is from center to the perimeter.

In this case the radius is 21in.

3.14 for pi

C = 2(21)(3.14)

C = 42(3.14)

C = 131.88in
