you divide the surface area by the circumference.
To find the area of a circle knowing only the circumference, you can use the formula A = (C^2) / (4π), where A is the area and C is the circumference. Square the circumference, then divide it by 4π to get the area.
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
If the object is a circle and if 9.5 is the diameter, the area is 70.88 and the circumference is 29.85
If the object is a circle and if 24 is the diameter, the area is 452.39 and the circumference is 75.4
Area = circumference squared... You do circumference divided by 4,... and then divide that by Pi.
you divide the surface area by the circumference.
The circumference is: 32.1

The area of a circle when the circumference is 10 inches is: 7.96 square inches.
Circumference = 2*pi*radius Area = pi*radius2
Circumference = 2*π*r where r is the radius So r = circumference/(2*π) Then Area = π*r2
What do you have? The area of the circle or the circumference? Area: divide the area by pi, then square root it Circumference: divide the circumference by 2 then divide it by pi
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
