Radius = circumference/pi
Radius = square root of (area/pi) Circumference = 2*pi*radius
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
2 x pi x radius
find the radius of a circle with circumference of 42.1
Circumference = 2*pi*radius So Radius = Circumference/(2*pi)
Radius = Circumference/(2*pi)
Radius = circumference/pi
bu
Radius = square root of (area/pi) Circumference = 2*pi*radius
Divide the circumference by (2*pi)
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
2 x pi x radius
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
