Answer: 113 (rounded)

Explanation:

Hey!

So for this we just use our sphere formula and follow the steps.

Volume= 4/3 πr^3

R= radius (half of diameter)

For pi we are going to use 3.14.

Let’s work this out now.

Radius is 3 so since it is cubed, we multiply it by itself 3 times. We get 27. Now, let’s multiply this by 3.14 and get 84.78.

Lastly, multiply by 4/3. We get 112.9333. This is the volume.

Hope this helped! :D

Sorry I messed any thing up!

Answer:

113

Explanation:

The volume of a sphere is
(4)/(3)\pi r^3, where
r is the radius of the sphere. The radius of the given sphere is 3 ft, so its volume is
(4)/(3) \pi \cdot 3^3 = 36\pi. Using 3.14 for
\pi, this is approximately equal to 113.04. Rounding to the nearest whole number, the answer is 113 cubic feet.
