A = C^2/(4 pi)
The area of the circle is...
The circumference squared...
divided by 4...
divided by pi
If you already know the area, then you can multiply it by 4*pi, and then the square root of the product is equal to the circumference!
C = (A*(4 pi))^(1/2)
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
Radius = square root of (area/pi) Circumference = 2*pi*radius
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
S = C2/pi where S is the surface area, C is the circumference.

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.
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
S = C2/pi where S is the surface area, C is the circumference.
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
Times length times width
Area = Circumference squared divided by 4pi.
If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.
The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.
Given the radius, r, the area is pi*r^2.If given the diameter d, the radius is d/r so the area is 0.25*pi*d^2If given the circumference, c, the radius is c/(2*pi), so area = 0.25*(c^2)/pi
The circumference is 4pi
