Tranquility:

Volume of a sphere = \(\large \frac{4}{3} \pi r^3\)

joshiscool:

Thats the answer?

Tranquility:

No, you must plug in your r. r is the radius of the sphere, and in your case r = 6.5 feet

Bob:

4/3(3.14)(6.5)^3 simplify it

Bob:

or solve

joshiscool:

1149

joshiscool:

Thats not a option on the list

Tranquility:

Don't evaluate it with \(\pi\) because the answer choices include it.

Tranquility:

4/3 * (6.5)^3 * \(\pi\)

joshiscool:

1150

Tranquility:

What is 4/3 * (6.5)^3

joshiscool:

366

Tranquility:

And this means that \( \Large \text{Volume} = \frac{4}{3}(6.5)^3 \pi = 366.\bar{16} \pi\)
