How do you find the radius using the circumference?
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)=
A circle has a circumference of 16 pi inches what is its radius?
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.
If circumference is 24 what is radius?
Circumference = c = 2*pi*r; therefore r = c/(2*pi) or 24/(2*pi) or 12/pi or approximately 3.81972
What is the radius of a circle that has the same area and 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.
What is the formula for circumfrence?
Circumference of a circle = 2*pi*radius or pi*diameter
How do you find the radius of a circle if all you know is the circumference?
C = circumference r = radius C = 2 x pi x r C / 2 = pi x r C / 2 / pi = r
What is the radius of a circle with circumference of 8 inches?
C = 2*pi*r 8 = 2*pi*r 4 = pi*r r = 4/pi

C equals 2pei R find for R?
Presumably C means circumference and R means radius? If C = 2*pi*R Then R = C divided by 2*pi
If circumference is 24 what is radius?
Circumference = c = 2*pi*r; therefore r = c/(2*pi) or 24/(2*pi) or 12/pi or approximately 3.81972
How do you find area from circumference?
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.
The circumference of a circle is 60 pi cm what is the radius of the circle?
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
What is the radius of a circle that has the same area and 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.
What is the approximate radius of a circle who circunfrance is 45.53 kilometers?
circumference(c)= 2 * pi * radius (r) r = c / ( 2 * pi ) r = 45.53 / 2 * pi r = 7.246 (approx)
How do you find the curcunfrunce of a circle?
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.
Can the circumference and the area of a circle both have the same answer?
C=2(pi)r A=(pi)r2 If C=A, then 2(pi)r=(pi)r2. Divide both sides by r: 2(pi)=(pi)r. Divide both sides by (pi): 2=r. Therefore, if the radius of a circle is 2 ft., the circumference is 2 sq. ft.
