Answer:
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
