The circumference of a circle is a distance. It's the distance you would drive to go around the circle.
If you straighten it out, you have a line. It's a simple length, and doesn't involve squares or cubes.
If they give you the radius of a circle and u want to find the circumference u have to do
2* TT* r and if they give u the diameter u do TT*d

Area of a Circle using Function in C?
To find the area of a circle using the circumference, you need to use the formula Area=Circumference squared divided by four times pi. For this type of equation, pi would be equal to 3.14.
How do you get a circumference of a circle?
to get the circumference of a circle you must multiply pi times diameter so say the circle's diameter was 8, you would do you 8 x pi (3.14 in this case) = 25.12 . that would be the circumference. the formula is circumference = pi (3.14) x diameter ! here's some extra information, to get the area of a circle you have to multiply pi and the radius of the circle squared. so say the circles radius is 2, then you have to square 3 which is 9. to square a number you have to take that number and multiply it by itself , in this case i did 3x3 to get the radius squared. OK, so now that i have the radius squared you need to multiply it by pi. which is 3.14 , so 9 x 3.14 = 28.26 the formula is area = pi x radius squared.
What is the diameter of a circle with a circumference of 5?
Since the circumference is equal to the diameter times pi, you need to divide the circumference by pi in this case.
What is the diameter of a circle with 52cm as circumference?
16.55cm - If you want to work it out, you will need to divide the circumference by pi.
You have the circumference and you need to know the diameter?
The formula for finding circumference is 2∏r (or ∏d). So to find the diameter, you would divide the circumference by pi (3.14, approximately).
