A right cylinder has a radius of 4 and a height of 11. What is its surface area?
The area of the cylinder is 375.52 square units.
For a cylinder of radius R and height H, the surface area is:
\(A = 2*(pi*R^2) + 2*pi*R*H\)
In this case:
Replacing that in the area equation we get:
\(A = 2*(3.14*4^2) + 2*3.14*4*11 = 375.52\)
So we conclude that the area of the cylinder is 375.52 square units.
