It has the square in the corner meaning it is a right triangle, it only needs one right angle to be a right triangle. So you can say that is a shortcut.

How many cubic inches of material do you need to make a solid rubber ball with diameter<br> of 3

Lera25 [3.4K]

Answer:

Step-by-step explanation:

What we're looking for here is the volume of this ball, which is the volume of a sphere:

$V=\frac{4}{3}\pi r^3$

If our diameter is 3, then the radius is 1.5:

$V=\frac{4}{3}\pi (1.5)^3$

In terms of π, the solution is

$4.5\pi$ which can also be expressed as $\frac{9\pi }{2}$

Or if you have to multiply in the pi, the solution is

V = 14.14 cubic inches
