Example 3: Find the surface area of a cylinder whose radius is 7 units and height is 11 units. Solution: Surface area of cylinder = 2πr(h + r) = 2 × 3.14 × 7 × (11 + 7) = 791.28 square units. Similarly, you can use the calculator to find the surface area of the cylinde...
Therefore, the total surface area of the cylinder, call it S.A. is: S.A. = 2 × pi × r2+ 2 × pi × r × h A couple of examples showing how to find the surface area of a cylinder. Example #1: Find the surface area of a cylinder with a radius of 2 cm, and a height o...
Example: The diameter of the base of a cylinder is 12 cm and the height is 8 cm. Find the surface area of the solid cylinder. Solution: Radius = 6 cm Surface area = 2πr (r + h) = = 528 cm2 How to derive and use the formula of the surface area of a cylinder?
Surface Area of a Cylinder: Examples Some examples of solving the surface area of a cylinder are presented below. Example 1 What is the surface area of a cylinder with a height of 10 inches and a radius of 3 inches? Assume a value of 3.14 for π and round the answer to the nearest ...
