Question

In terms of pi, what is the volume of the sphere?

9 pi cubic meters
30 pi cubic meters
36 pi cubic meters
72 pi cubic meters

Answer 1

Hi!!

The correct answer is listed below:

A. 9 pi cubic meters

B. 30 pi cubic meters

C. 36 pi cubic meters

D. 72 pi cubic meters

Answer 2

C

Explanation:

The volume of a sphere can be found using:

v= 4/3 π r^3

We are given the radius in the picture, and it is 3. Therefore, we can substitute 3 in for r

v= 4/3 π 3^3

Evaluate the exponent first

v= 4/3 π 27

Since we are finding the answer in terms of pi, we can simply multiply 4/3 and 27 and leave the pi.

v= 36 π

So, our volume is 36π cubic meters/meters^3, or choice C
