Hello!

First you have to find the volume of the cylinder

To find the volume of a cylinder you use the equation

$V = \pi r^{2} h$

V is volume
r is radius
h is height

Put in the values you know and 3.14 for pi

$V = 3.14 * 3^{2} * 7$

Square the number

V = 3.14 * 9 * 7

Multiply

V = 197.82
------------------------------------------------------------------------------------------------------
Next you find the volume of the sphere

To find the volume of a sphere you use the equation

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

V is volume
r is radius

Put in the values you know and 3.14 for pi

$V = \frac{4}{3} * 3.14 * 3^{3}$

Cube the number

$V = \frac{4}{3} * 3.14 * 27$

Multiply

V = 113.04
------------------------------------------------------------------------------------------------------
Finally you subtract the two volumes from each other

197.82 - 113.04 = 84.78
------------------------------------------------------------------------------------------------------
The answer is C)84.78

Hope this helps!
