Question

The diameter of a volleyball is 8.15 inches. What is the volume of the ball,

Answer 1

Answer:

B.  283.45 cubic inches.

Step-by-step explanation:

We know that a volleyball has spherical form.

To find the volume of a sphere, we have the following formula

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

Now, we know that the radius is defined as half the diameter

$r=\frac{d}{2} \\r=\frac{8.15in}{2}\\ r=4.075in$

Then, we replace the radius to find the volume of the ball

$V_{sphere}=\frac{4}{3} (3.14) (4.075in)^{3}=283.45 in^{3}$

Therefore, the right answer is B.  283.45 cubic inches.

Answer 2

Answer:

Volume

≈  283.49n

So B. 283.45in
