What is the surface area of a cylander round to the nearest tenth the height is 9ft and the radius is 3ft

Answer

72pi feet^2 or about 226 feet^2

Step-by-step explanation:

The shape has a side, which is now found my the circumference, multiplied by the height.

Circumference=2*pi*r

r=3 so 6pi is the circumference

Times the height is

6pi*9

54pi is the side

now add the two surfaces left, the top and bottom, which is the area of the circle, which is found with pi*r^2

pi*3^2 is 9pi, there is two of them so add 18pi to the 54pi, which is 72pi.

Pi is about 3.14 so the rounded answer is 226.
