area of a circle = pi*r^2

with pi being 3.1415926535..... that is the ratio between the diameter of the circle and it's circumference.

r stands for radius (half the diameter if you didn't know)

so for this circle to find the area all you have to do is 12 (half of 24 the diameter to find the radius) , then square it (144) then times it by pi which equals approximately 452.39 meters^2

How do you get the circumference out of the area?

you divide by pi (3.14) then take the square root, then multiply by 2 and multiply by pi (3.14)...in that order i.e. if you have a circle with area of 314 square inches, you take the 314 and divide by 3.14...you get 100...then you take the square root of 100...you get 10...then you multiply by 2...you get 20...then you multply by 3.14...you get 62.8 inches...thats the circumference of a circle with an area of 314 square inches
