Find the area of the top and bottom circle, then, multiply the height of the cylinder by the circumference of one circle. Add that all together to get the answer.

Example: Height; 5 in.

Diameter (of circle); 7 in.

Area of circles: pi x radius squared i.e. pi x 3.5 squared = 38.425 x 2 = 76.93

Area of rectangle: pi x diameter i.e. pi x 7 = 21.98 x height (5) = 109.9

Surface Area: 109.9 + 76.93 = 186.83.

What exactly do you mean? Area? πr^2 Circumference? πd example:

A= 2(3.14)9 squared 2

=6.28(81)

=508.68 un.

What is the radius and height of cylinder with a surface area of 32 square feet?

The surface area does not provide enough information to determine the dimensions of the cylinder. It could be a tall thin cylinder or a squat one. It is possible for two such to have the same surface area but vastly different volumes.

How do you find the curved surface area of a cylinder?

1. Find the surface area of the whole cylinder 2. Find the area of one of the two circles on either end of the cylinder 3. Multiply the circle's area by two and subtract their area from the total surface area 4. Now you have the surface area of an unclosed cylinder!
