multiply by 2 then times pie
nfughs
Multiply the radius by 2 x pi.
Circumference = 2 pi x radius = 6 pi = 18.85 m (rounded)
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.

Circumference = 2 pi x radius = 6 pi = 18.85 m (rounded)
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
Circumference = 2*pi*radius So Radius = Circumference/(2*pi)
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.
The circumference of a circle if the if the radius is 6 cm is: 37.7 cm
A circle with a radius of 6 feet has a circumference of 37.7 feet.
find the radius of a circle with circumference of 42.1
Circumference = 2 x Pi x Radius Radius = Circumference / (2 x Pi).
Circumference of a circle = 2*pi*radius
To find the circumference of a circle, use the equation: Circumference = 2*π*radius so when the radius is r, the circumference is 2πr
