Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
find the radius of a circle with circumference of 42.1
To find the circumference of a circle, use the equation: Circumference = 2*π*radius so when the radius is r, the circumference is 2πr
Diameter = circumference/pi Radius = circumference/2*pi
Diameter = radius * 2 Circumference = pi * diameter.
Circumference of a circle: 2*pi*radius or diameter*pi
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
Circumference = 2*pi*radius So Radius = Circumference/(2*pi)
find the radius of a circle with circumference of 42.1
Circumference = 2 x Pi x Radius Radius = Circumference / (2 x Pi).
To find the circumference of a circle, use the equation: Circumference = 2*π*radius so when the radius is r, the circumference is 2πr
Circumference of a circle = 2*pi*radius
Circumference = 2 * radius * pi (where pi is approx = 3.14159)So Radius = Circumference / (2 * pi)
Diameter = circumference/pi Radius = circumference/2*pi
circumference = pi * 2radius (diameter) so to find radius you use circumference/(2 x pi) this will find radius ----
Diameter = radius * 2 Circumference = pi * diameter.
Circumference=2*pi*radius
