Question

The radius of a circle is 9 centimeters . What is the circumstance?

Answer 1

Answer: 56.52

Explanation:

In order to find the circumstance, we will need to use this formula:

2πr

(2)(3.14)(9)

6.28 x 9

= 56.52 cm

Answer 2

C = 18 pi cm or approximately 56.52 cm

Explanation:

The circumference is given by

C = 2* pi*r

C = 2 * pi*9

C = 18 pi

Using 3.14 as an approximation for pi

C = 18*3.14

C =56.52
