What is the volume of a cylinder with a diameter 30 inches and a height of 5.5 feet?

Answer 1

The formula for volume of a cylinder is V = A x H where A is the surface area and H is the height of the cylinder. The formula to find the area is A = Pi x R² where Pi is 3.1416 and R² is the radius squared (multiplied by itsellf) {the Radius is 1/2 of the diameter}. Note that you have inches and feet in your cylinder, you need to convert inches to feet to solve. 30 inches = 2.5 ft. Now to find the area: A = Pi x R² A = 3.1416 x (1.25 x 1.25) A = 3.1416 x 1.5625 A = 4.90875 sq ft Now to find the volume V = A x H V = 4.90875 x 5.5 V = 26.998125 cu ft
