Divide the circumference by the value Pi - this will give you the diameter.
find the circumference of the circle and multiply it by the height of the cylinder
you divide the surface area by the circumference.
Find the radius by dividing the circumference by 2pi then find the area of the base and multiply it by the height
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
Pi X D = Circumference. To find Diamater if you know Circumference, divide Circumference by Pi (3.14).
C = 2pi * r
If you mean the volume of a cylinder then divide the circumference by 2*pi to find its radius and so:- Volume in cubic units of the cylinder = pi*radius squared*height
Take the circumference and multiply it by it's height to get the lateral surface area.
divide the circumference by pi (3.1416) and divide the product by two that will give you the radius
2(pi)r=2X3.14X3cm=18.85cm to four significant figures
height * circumference (picture the cylinder cut along the long edge, then rolled out flat, and you would measure height * width) note: if you need to include the circles at the top and bottom of the cylinder, add (circumference / 3.1415926 )^2 * 2 * 3.1415926
We assume the surface area of a cylinder excluding its ends. Area = height of cylinder multiplied by circumference. That is A = h x Pi x diameter.
