C = 2∏r is the formula for calculating the circumference of a circle
The equation for circumfrance is 2(pi)r (pi meaning the constant 3.14159, rounded). To find the radius if the circumfrance is known, you would re-arrange this equation to solve for r - it would go from C=2(pi)r into r=C/2(pi). c = circumference, r = radius. If the circumference is 2*pi*r, then r = c/(2*pi)=
The formula where C=circumference, R=radius is C = 2 pi R Since C = 16 pi inches and 16 pi = 2 pi R we can solve for R and get R= 16 pi /2 pi = 8 Therefore the Radius is 8 inches.
Circumference = c = 2*pi*r; therefore r = c/(2*pi) or 24/(2*pi) or 12/pi or approximately 3.81972
Circumference, C = 2*Pi*R Area, A = Pi * R^2 A = C Pi * R^2 = 2*Pi*R --> solve for R (radius) R = 2 So, the radius of a circle with area = circumference is two.
Circumference of a circle = 2*pi*radius or pi*diameter
C = circumference r = radius C = 2 x pi x r C / 2 = pi x r C / 2 / pi = r
C = 2*pi*r 8 = 2*pi*r 4 = pi*r r = 4/pi

Presumably C means circumference and R means radius? If C = 2*pi*R Then R = C divided by 2*pi
Circumference = c = 2*pi*r; therefore r = c/(2*pi) or 24/(2*pi) or 12/pi or approximately 3.81972
To find the area of a circle from its circumference, you can use the relationship between the two. The circumference (C) is given by the formula ( C = 2\pi r ), where ( r ) is the radius. First, solve for the radius by rearranging the formula: ( r = \frac{C}{2\pi} ). Then, use the area formula ( A = \pi r^2 ) to find the area by substituting the radius you calculated.
Divide the area by pi. Find the square root of your result. Multiply this by 2. Now multiply this by pi. There is your circumference.
let c bet the circumference and r be the radius. c = 2 pi r since c is 60 pi 60pi = 2 pi r divide both sides by 2 pi 30 = r
To find the circumference of a circle, you can use the formula ( C = 2\pi r ), where ( C ) is the circumference and ( r ) is the radius of the circle. Alternatively, if you know the diameter ( d ) (which is twice the radius), you can use ( C = \pi d ). Simply multiply the radius by ( 2\pi ) or the diameter by ( \pi ) to get the circumference.
Circumference, C = 2*Pi*R Area, A = Pi * R^2 A = C Pi * R^2 = 2*Pi*R --> solve for R (radius) R = 2 So, the radius of a circle with area = circumference is two.
circumference(c)= 2 * pi * radius (r) r = c / ( 2 * pi ) r = 45.53 / 2 * pi r = 7.246 (approx)
