The surface area of a shape is the sum of the area of all of its faces. To find the area of a cylinder, you need to find the area of its bases and add that to the area of its outer wall. The formula for finding the area of a cylinder is A = 2πr2 + 2πrh.
Step-by-step explanation:
Surface area of a cylinder = 2πr 2 + 2πrh
Volume of a cylinder = πr 2 h
You need to know the radius and height to figure both the volume and surface area of a cylinder.
Answers for volume problems should always be in cubic units.
Answers for surface area problems should always be in square units.
