The radius of a circle whose circumference is 40pi is 20 units.
Circumference = 2*pi*r = 125.66 metres
The radius is 1/2 of the circumference.
If the circumference is 34.54, the radius is 5.497211734394065.
If the circumference of a circle is 351.68 the radius is: 56
Circumference is 2 x pi x radius so.....
The radius of a circle whose circumference is 40pi is 20 units.
Circumference of a circle equals Pi times the double the radius C = 2 x 3.14 x radius C= 2 x 3.14 x 20 C = 125.6 The circumference of a circle with a 20 foot radius is 125.6 feet.
The circumference is 20 times pi or appromixately 62.8.
The radius of this circle is 10 units.
radius = 20/(2*pi) = 3.183098862 inches
Circumference = Pi * diameter. so Circumference = pi * 20 = 62.832
20
Multiply the radius by (2 x pi).
Circumference = 2*Ï€*radius = 20*Ï€ feet
Circumference = 2*pi*r = 125.66 metres
Divide the circumference by (2 x pi).
