Asap this is stressing me out!
a right circular cylinder has a surface area of 96π in2 and a radius of 4 in. what is the height of the cylinder?
a. 8 in.
b. 6 in.
c. 16 in.
d. 24 in.

The surface area of a right cylinder is the sum of the areas of the lateral face and the circular bases. The lateral face is really just a rectangle with the same height as the cylinder and a length equal to the circumference of the circular base.

If the radius of the base is and the height is , then the surface area of the cylinder is



You're given that the area is and the radius is , so you have
