WebThe circumference is pi times the diameter if it were opened up and straightened out to a line segment. The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large.
WebL = 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) ** The area calculated is only the lateral surface of the outer cylinder wall. To calculate the total surface area you will need to also calculate the ...
