Question

Geoffrey needs to find the circumference of a circle. Which process should he use?

A He should multiply the diameter times 2 and then multiply the result by 3.14.

B He should multiply the radius times 2 and then multiply the result by 3.14.

C He should square the diameter and then multiply the result by 3.14.

D He should square the radius and then multiply the result by 3.14.

Answer 1

The process he should use in order to find the circumference of a circle is that he should find the radius and multiply the radius by 2 and then afterwards multiply the product by pi or 3.14. This is because the circumference of a circle is formulated as C = 2πr or C = 2(3.14)r.

Explanation

with that being said the answer should be B

Answer 2

`2 * 3.14 * radius`

B
