Answer:
The second choice is the same so it is the last one
The best apporximation for the volume of this ball is 382 cubic inches.
<h3>What is the volume of the ball?</h3>
The volume of the ball is calculated by the formula V = 4 / 3πr³. This formula is the same in the whole world.
Given
A regulation basketball has a diameter of about 9 in.
The radius of the ball is;
The volume of the ball is;
Hence, the best apporximation for the volume of this ball is 382 cubic inches.

This is a classic example of a 45-45-90 triangle: it's a right triangle (one angle of 90) & two other sides of the same length, which means two angles of the same length (and 45 is the only number that will work). With a 45-45-90 triangle, the lengths of the legs are easy to determine:
45-45-90
1-1-sqrt2
Where the hypotenuse corresponds to sqrt2.
Now, your hypotenuse is 10.
To figure out what each leg is, divide 10/sqrt2 (because sqrt2/sqrt2 = 1, which is a leg length in the explanation above).
Problem: you can't divide by radicals. So, we'll have to rationalize the denominator:
(10•sqrt2)/(sqrt2•sqrt2)
This can be rewritten:
10sqrt2/sqrt(2•2)
=10sqrt2/sqrt4
=10sqrt2/2
=5sqrt2
Hope this helps!!
