r=d/2
c=Pi*d
2*r=d
c=Pi*2*r
where c is the circumference r is the radius and d is the diameter

How do you find the curcumference of a circle?
you times it by 3.14 but if you get a radius you timesit by 2, then by 3.14
How do you find out the radius of a circle?
The radius of a circle is half its diameter (the measure of the circle from one side across to the other).
Describe the effect on the area of a circle when the radius is doubled?
the radius is from the center of the circle to the edge so that's how you find the radius.
What is the radius of a circle if the area is 153.86cm2?
The area of a circle is 153.86cm².find the radius of the circle
What would be the radius of a circle with a diameter of 8 inches?
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
How do you find the curcumference of a circle?
you times it by 3.14 but if you get a radius you timesit by 2, then by 3.14
What is the curcumference of a circle with a 16 meter radius?
Well first you find on your calculator you need to find pi which looks something like this π. Now to find the curcumference of any circle the formula is pi multiplied by the diameter. The radius is 16 metres, and the diameter of any circle in life is two multiplied by the radius. So you do π times by 32 which equals 100.53(I rounded it off to the nearest 2 decimal places). or even easier 3.14 x radius 2 l l l PI times raduis 2 and now for area 2 times 3.14 times raduis
A circle has a curcumference that measures 18pi inches. What is the radius in inches of the circle?
Circumference equals 2 X pi X radius, so work backwards. 18pi=2 X pi X radius divide pi. 18= 2 X radius divide by 2. radius= 9.
What is the radius if the curcumference is 23 inches?
Assuming we are talking about a circle... C = 2xpixr 23 = 2 x pi x r r = 23/(2xpi)
How do you find the radius of a circle with the circumference in terms of pi?
find the radius of a circle with circumference of 42.1
The area of circle if its curcumference is 14?
formula for circumference is : C= pie (times) diameter 14= pie Diameter 14=3.14 diameter so divide by pie on both sides to find the diameter aprox: 4.456 = diameter formula for area is : a= pie radius ^2 so find the radius which is half the diameter 4.456/2 =2.228 = radius square the radius 2.228^2= 4.964 times by pie area= 15.597
How do you find the radius of the base in a cylinder?
It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.
How do you find the director circle of circle?
The director circle of a circle with radius r is a concentric circle with radius r*sqrt(2).
How do you find the radius of a circle if you know the radius?
You already know the radius.
How do you find distance if radius is given?
Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
How do you find what a diameter of a circle is?
It is twice the radius of a circle
How do you find out the radius of a circle?
The radius of a circle is half its diameter (the measure of the circle from one side across to the other).
