Question

A sphere has a diameter of 10 in. What is the volume of the sphere?

Answer 1

Answer:

The volume of sphere is 500 in³

Step-by-step explanation:

Given:

Diameter of sphere is 10 in.

Now, to find the volume we need radius.

Radius(r) = half of the diameter

$r=\frac{10}{2}$

$r=5$

And, now putting the formula to get the volume of sphere:

$volume(v)=\frac{4}{3}\pi r^{3}$

Putting the value of π = 3.

$v=\frac{4}{3} \times 3.14\times 5^{3}$

$v=1.33\times 3.14\times 125$

$v=522.025$

So, the volume is 522.025 in³.

By estimating the value the volume is 500 in³.

Therefore, the volume of sphere is 500 in³.
