This surface area of a cylinder calculator is a handy tool that quickly finds all of the three types of surface areas: The base surface area of a cylinder; The lateral surface area of a cylinder; and; The total surface area of a cylinder.
The surface area of a cylinder is equal to the sum of its curved surface area and circular bases area. Learn to derive the formula for cylinder’s surface area and solved examples at BYJU’S.
The surface area (also known as the total surface area) of a cylinder of radius 'r' and height 'h' is 2πr(r+h) whereas the curved surface area of a cylinder is 2πrh. Learn how to these formulas are derived.
The surface area of a cylinder is the total space occupied by the flat circular bases of the cylinder and the curved surface. Simply, it is the sum of an area of a circle, since the base of the cylinder is a circle and the area of the curved surface which is a rectangle.
The surface area is equal to the sum of the areas of the two circular bases and the rectangular side. The area of each base is \pi r^2. πr2. Since the width of the rectangular side must be equal to the circumference of the base, the area of the rectangular side is 2\pi rh. 2πrh.
Use the calculator above to calculate height, radius or surface area of a cylinder. Enter any two values and the missing one will be calculated. For example: enter the radius and height, and press 'Calculate'. The surface area will be calculated.
Calculate the lateral surface area of a cylinder (just the curved outside)**: L = 2 π rh. Calculate the top and bottom surface area of a cylinder (2 circles): T = B = π r 2. Total surface area of a closed cylinder is: A = L + T + B = 2 π rh + 2 (π r 2) = 2 π r (h+r)
