Following the equation for a circumference, C being
C= pie. * d
This can be rearragend so d the diameter to be in terms r, raduis
C=pie. * 2r
This then can be rearraged to
r= C / (2*pie.)

How do you find the radius of a circle if you know the circumferance?
radius = circumference/2*pi
What is the circumference of a semi circle with a six inch radius?
find the circumferance as if it was a whole circle but when you get the answer divide it by 2
How do you find the radius of a circle with a circumferance of 70 inches?
divide the circumference by 3.14 to get the diameter - then divide that by 1/2 to get the radius Radius = Circumference / 2 x pi from C = Diameter x pi
What is the circumferance of a circle of which the radius is 6 yards?
The circumference is approximately 37.7 yards.
If the diameter of a baseball is 3 inches what is the circumference?
The circumferance is found by using the formula 2(r)(pi). r stands for the radius. The diameter, which is already given in the problem, is two time radius. Therefore the only thing you really have to do is multiple the diameter= 3 inches by pi. Circumferance is 9.425 inches.
How do you find the radius of a circle if you know the circumferance?
radius = circumference/2*pi
How do you get the radius from the circumference?
The circumferance of a circle is equal to 2 x pi x r, where r is the radius, i.e. approximately 6.2832 than its radius. Divide the circumferance from the figure above to get the radius of a circle in which the circumferance is known.
What is the circumference of a semi circle with a six inch radius?
find the circumferance as if it was a whole circle but when you get the answer divide it by 2
How do you find the radius of a circle with a circumferance of 70 inches?
divide the circumference by 3.14 to get the diameter - then divide that by 1/2 to get the radius Radius = Circumference / 2 x pi from C = Diameter x pi
What is the circumferance of a circle of which the radius is 6 yards?
The circumference is approximately 37.7 yards.
Formula to find circumferance given diameter?
Radius is half of the diameter, so you can easily come up with a formula: L = 0.25 * pi * d2
What is the circumferance of a seven eighths inch circle?
7/8 inch circle has a diameter of 7/8 and a radius of 7/16=.4375 circumferance of a circle = 2*pi*radius = 2*3.14*.4375 =2.7475 or 7*pi/8
The radius of a circle with a circumference?
R(10) If you know the Circumferance, divide it by Pi (about 3.14). That will tell you the diameter. Half the diameter equals the radius.
What is the formula for finding the circumferance of a circle?
Either pi times the diameter or pi times twice the radius (which is the diameter)
If the diameter of a baseball is 3 inches what is the circumference?
The circumferance is found by using the formula 2(r)(pi). r stands for the radius. The diameter, which is already given in the problem, is two time radius. Therefore the only thing you really have to do is multiple the diameter= 3 inches by pi. Circumferance is 9.425 inches.
What is the circumferance of the moon?
The circumferance of the moon is 6790 miles.
How can you find the circumference if you know what the diameter is?
Use the formula : pi * radius * radius = circumferance. (the radius is half of the diameter).A2The above answer will give you the area, not the circumference. To get the circumference from the diameter just multiply by pi. Circumference = pi x Diameter.i agree, very ezyou know everything is not always ez pz i am in sixth grade even my mom does not know it.
