Question

What is the exact volume of the sphere?

Answer 1

We know, Volume of a Sphere = 4/3 πr³
V = 4/3 * π * (12.3)³
V = 4/3 * π * 1860.71
V = 2481.156π cm³

In short, Your Answer would be Option A

Hope this helps!

Answer 2

Answer:

volume of Given sphere with radius 12.3 cm is 7790.83 cm³

Step-by-step explanation:

Given  : as sphere with radius 12.3 cm

We have to find the exact volume of the sphere.

Consider the given sphere with radius 12.3 cm

Volume of sphere = $\frac{4}{3} \pi r^3$

We have r = 12. cm

So substitute, we get,

Volume of sphere = $\frac{4}{3}\cdot \pi \cdot (12.3)^3$

Simplify, we get

Volume of sphere = $\frac{4}{3}\cdot \pi \cdot 1860.867$

Using $\pi=3.14$ , we have,

Volume of sphere = $\frac{4}{3}\cdot 3.14 \cdot 1860.867$

Volume of sphere = $\frac{4}{3}\cdot 5843.12238$

Volume of sphere = 7790.829 cm³

Thus, volume of Given sphere with radius 12.3 cm is 7790.83 cm³
