Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius2

Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).

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

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

Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or pi*diameter

Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).

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

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

Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius2

The formula for the area of a circle is pi * radius squared. The circumference of a circle's formula is pi * diameter. NOTE: pi equals approx. 3.14

The area of a circle that has a circumference of 16pi is: 201.1 units2

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