Question

The radius of a sphere is 6 units.

A sphere has a radius of 6 units.


Which expression represents the volume of the sphere, in cubic units?

Three-fourthsπ(6)2
Four-thirdsπ(6)3
Three-fourthsπ(12)2
Four-thirdsπ(12)3

Answer 1

B

Explanation:

Answer 2

Answer: Four-thirdsπ(6)³

Step-by-step explanation: The formula for the volume of a sphere is attached in the image down below.

Notice that two of the options listed have three-fourths but we use four-thirds to find the volume of a sphere. This means that we can eliminate the 1st and the 3rd option.

Now, we will multiply that by π and then by the radius cubed which is also written as 6³. This means that our answer would be the second option.
