Circumference = 2*pi*radius
So
Radius = Circumference/(2*pi)
by timesing the circumference by pie
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
Well, isn't that a happy little question! To find the radius when you know the circumference, you can use the formula: circumference = 2 * π * radius. So, if the circumference is 48 inches, you can divide that by 2π to find the radius. Just remember, there are no mistakes, only happy accidents in math and in art!
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
