To expand, use distributive property:
(x - 5)(x + 4)

Simplify by adding like terms:
x^2 - x - 20

What is the volume of a cylinder with the base radius of 10 units and a height of nine units?
Otrada [13]

Answer:

V = 2827.43\ units^3  or V = 900\pi\ units^3

Step-by-step explanation:

The volume of a cylinder is calculated by the following formula

V = \pi r^2 *h

Where r is the radius of the cylinder and h is the height

In this case we know that the radius r of the base is:

r=10\ units

and

h=9\ units

So the Volume is:

V = \pi (10)^2 *9

V = 900\pi\ units^3

V = 2827.43\ units^3
