Question

Please help i really need it

Answer 1

Answer:

500 in^3

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

Using 3 for pi

V = 4/3 (3) (5)^3

V = 4 * 125

V = 500

Answer 2

Answer:

500 cubic inches

Step-by-step explanation:

To find the volume of a sphere, you have to use the equation

$V = \frac{4}{3} \pi r^3$ <-- Where V stands for volume, and r stands for radius

Using the radius of 5 shown in the picture, we can insert it into the equation to get:

$V = \frac{4}{3} \pi *5^3$

$V = \frac{4}{3}\pi *125$

The picture also tells us to use 3 for pi, so we can insert that into the equation as well.

$V= \frac{4}{3} * 3 * 125$

$V = 500$

Now that we have the volume, we just have to add the unit, which will be cubic inches, since the unit that the length is measured in is inches, and volume is three-dimensional, which means the inches will be cubic.
