Area = pi*72 square cm Circumference = pi*14 cm
Circumference: 14*pi mi Area: 49*pi square mi
Circ = 14 pi in, area = 49 pi sq in.
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius2
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or pi*diameter
Area = pi*72 square cm Circumference = pi*14 cm
Circumference: 14*pi mi Area: 49*pi square mi
Circ = 14 pi in, area = 49 pi sq in.
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
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 of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or pi*diameter
Area = (Circumference squared)/4 pi Circumference = 2 sqrt(Area times pi)
circumference = pi*diameter So diameter = circumference/pi = 14*pi = 4.46 cm
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
