Circumference = 2*pi*radius or pi*diameter
Circumference = 36pi inches
36*pi inches
The circumference C = 2 r times pi C = 76 inches times pi. pi = 3.141592654...
pi = circumference/diameter circumference = pi*diameter or 2*pi*radius
Using the circumference, you would find the radius first. The circumference C = 2*Pi*r where r is the radius. Then, the area of the circle = Pi*r^2.
Circumference of a circle = diameter*pi
Circumference = 2*pi*radius = 26*pi inches
36*pi inches
Circumference = 2*pi*r = 34*pi inches.
The formula for the circumference of a circle is C = pi r2 where r is the radius. Substituting 56 inches for the radius gives: C = pi(56)2 = (3136)pi inches.
The circumference of a circle is its diameter times pi, which is the same as twice the radius times pi.A = 2r (pi)In this instance, the circumference is 32(pi) inches(about 100.53 inches)
The circumference C = 2 r times pi C = 76 inches times pi. pi = 3.141592654...
The formula for finding the circumference is the diameter times pi because the radius is half of the diameter, the diameter of this circle would be 8 8 times pi equals approximately 25.1327 Or you could leave it in terms of pi and say 8pi (using the symbol)
find the radius of a circle with circumference of 42.1
Area Diameter Radius Circumference
circumference = 2*pi*100
pi = circumference/diameter circumference = pi*diameter or 2*pi*radius
circumference = 2 * pi * radius circumference = 2 * 3.14 * 11.8 circumference = 74.104 Circumference = 2*pi*radius Circumference = 2*3.14*11.8 = 74.104 = 74.1 to the nearest tenth
