For a circle the diameter can be found by dividing the circumference by pi. Once the diameter is found by squaring the radius multiplied by pi.
For a cylinder follow the previous method and multiply the answer by two. Multiply the circumference of the circle by the cylinder height. Add the two answers together.
S = C2/pi where S is the surface area, C is the circumference.
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
you divide the surface area by the circumference.
Divide the surface area by the circumference of the circle, which is a product of the diameter x Pi. Essentially, an unrolled cylinder is a rectangle.
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference

Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
Take the circumference and multiply it by it's height to get the lateral surface area.
Find the radius by dividing the circumference by 2pi then find the area of the base and multiply it by the height
Radius = square root of (area/pi) Circumference = 2*pi*radius
You can not find the circumference when only area is given. you need other details relating to shape. minimum parameter should be provided to find the required parameter.
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
It should be relatively easy to find the surface area of a box when you are given the surface area.
The circumference is 24*Pi yards.The surface area = circumference x heightthereforeheight = surface area / circumference = 1206 sq.yd. / 24*Pi yd. = 15.9951 yards or 16 yards (rounded).
