Find the height of a cylinder with a surface area of 1,206.4 in^2 and a radius of 8 in.

h = 16 inches

Step-by-step explanation:

The surface area of a cylinder is given by

SA = 2 pi r^2 + 2 pi rh

We know the surface area and the radius

1206.4 = 2 ( 3.14) * 8^2 + 2 * 3.14 * 8 *h

1206.4 = 401.92+50.24h

Subtract 401.92 from each side

1206.4-401.92 = 401.92-401.92+50.24h

804.48=50.24h

Divide each side by 50.24

804.48/50.24 =50.24h/50.24

16.01273885=h
