Circumference of a circle = 2*pi*radius or diameter*pi

Area of a circle = pi*radius2

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.

area from circumference area = ( circumference2 / (4 * pi) ) area = 2.865 square feet (approx)

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 = 2Ï€r so r = circumference/2Ï€ Then area = Ï€r2

Circumference isn't squared OR cubed. However, Surface Area is squared and so is Area. So Circumference is just Circumference :)

Area = (Circumference squared)/4 pi Circumference = 2 sqrt(Area times pi)

the circumference and area of a circle with a diameter of elleven feet are as follow. circumference:34.54 area:94.985

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
