The diameter of a volleyball is 8.15 inches. What is the volume of the ball,
2 answers:
Answer:
<h2>B. 283.45 cubic inches.</h2>Step-by-step explanation:
We know that a volleyball has spherical form.
To find the volume of a sphere, we have the following formula
Now, we know that the radius is defined as half the diameter
Then, we replace the radius to find the volume of the ball
Therefore, the right answer is B. 283.45 cubic inches.

To convert from rectangular coordinate (x, y) to polar coordinate (r, θ).
r is given by the square root of the sum of the squares of the rectangular coordinate.
and θ is given by the arctan of the ratio of y to x.
Example:
To convert rectangular coordinate (3, 4) to polar coordinate
Therefore, rectangular coordinate (3, 4) = polar coordinate (5, 53.13°)
r is given by the square root of the sum of the squares of the rectangular coordinate.
and θ is given by the arctan of the ratio of y to x.
Example:
To convert rectangular coordinate (3, 4) to polar coordinate
Therefore, rectangular coordinate (3, 4) = polar coordinate (5, 53.13°)
