Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
28.26=area 18.84=circumference
circumference doesn't matter when solving for area..
The circumference of a circle is a line. Because it is a line it has no area, only length. So the area of the circumference cannot exist!
you divide the surface area by the circumference.
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
area = π x radius2 ⇒ radius = √(area ÷ π) circumference = 2π x radius ⇒ circumference = 2π x √(area ÷ π) ⇒ circumference = √(4π2 x area ÷ π) ⇒ circumference = √(4π x area) So knowing the area, the circumference can be calculated by taking the square root of the area multiplied by 4 times π Example: What is the circumference of a circle with area 78.54cm2 Circumference = √(4π x area) = √(4π x 78.54cm2) ~= 31.42cm
Area = circumference squared... You do circumference divided by 4,... and then divide that by Pi.
Area = (Circumference)2/(4*pi)
Circumference = 2πr so r = circumference/2π Then area = πr2
Circumference isn't squared OR cubed. However, Surface Area is squared and so is Area. So Circumference is just Circumference :)

the circumference and area of a circle with a diameter of elleven feet are as follow. circumference:34.54 area:94.985
Area = (Circumference squared)/4 pi Circumference = 2 sqrt(Area times 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
