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

The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.

you divide the circumference by pi to get diameter then divide that by 2 to get radius then square the radius and multiply it by pi

Radius x 2 x 3.14 = Area * * * * * That is the formula for the circumference! The area = pi*radius2

radius = circumference/(2*pi)area = pi*radius2So Area in terms of Circumference is A = pi [C/2pi]2or (circumference)2/4 pi

Pi as a fraction is 22/7 if converted to a decimal use as many decimal places as possible. It is usually used to calculate the circumference (perimeter) of a circle 2 x pi x r where r is the radius i.e distance from the centre to the circumference or to calculate the area pi x r x r Pi as a fraction is 22/7 if converted to a decimal use as many decimal places as possible. It is usually used to calculate the circumference (perimeter) of a circle 2 x pi x r where r is the radius i.e distance from the centre to the circumference or to calculate the area pi x r x r

you use pi to calculate the area or circumference of a circle

Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle

By dividing its circumference by 2*pi will give the radius of the circle and its area = pi*radius2

you divide the circumference by pi to get diameter then divide that by 2 to get radius then square the radius and multiply it by pi

Because of the radius of the circle

pi times diameter = circumference

There is no such thing as an "area of circumference".If 27 cm is the diameter, you can calculate the circumference by multiplying this by pi, which is approximately 3.1416.

Circumference C = 2 r times pi C = 119.38052083641213 centimeters. Area A = r2 times pi. A = 1134.0815 square centimeters.

The area of a circle (A) is pi x r x r.The circumference of a circle (C) is pi x d, or pi x 2r.So if you know C, you can calculate r using the formula C = pi x 2r or r = C/2piOnce you know r, you can calculate A using the formula A = pi x r x r

to calculate circumference you find a circles radius or diameter. you do diameter times pi or radius times 2 times pi. the you have circumference!
