If C is the circumference, then R = C/Pi
2
The circumference is 2 x pi x radius.
The radius is 18.
2 x pi x radius
Circumference = 2*pi*radius 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.
you do something to get the answer
Radius = Circumference/(2*pi)
The circumference is 2 x pi x radius.
Radius = 130.51 mm approx.
The radius is 18.
2 x pi x radius
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
The circumference of a circle is equal to 2 times pi times the radius of the circle. Therefore, if the radius of the circle is 10 inches, the circumference would be 2 times pi times 10 inches, or 20 pi inches. Pi is a mathematical constant with a value of approximately 3.14, so the circumference of the circle would be approximately 62.8 inches.
Circumference = 2*pi*radius Radius = Circumference/(2*pi)
if you want me to answer this i need to know the shape, or dimensions
The radius is 1/2 of the circumference.
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.
