How do you find a radius if you have the circumference?
You divide circumference / (2 x pi).You divide circumference / (2 x pi).You divide circumference / (2 x pi).You divide circumference / (2 x pi).
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 radius of a circle if the circumference is 62.8cm?
2*pi*radius = 62.8 cm Divide both sides by 2*pi to find the radius: radius = 9.994930426 cm
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 of a circle that has an area of 78 cm2?
Divide the area by the value of Pi to get the diameter. Divide the diameter by 2 to get the radius !
How do you calculate the area of a circle when you have the circumference?
you divide the circumference by pi to get diameter then divide that by 2 to get radius then square the radius and multiply it by pi
How do you find the radius of pi?
Divide it by 2
What is another way to find the area of a circle given the circumference?
Divide by pi to get the diameter. Divide the diamater by 2 to get the radius. Pi times radius squared.
How do you find a radius if you have the circumference?
You divide circumference / (2 x pi).You divide circumference / (2 x pi).You divide circumference / (2 x pi).You divide circumference / (2 x pi).
What is the answer for how much water in a 1inch x 100 foot pipe?
Volume of a cylinder = Pi x radius squared x height. Divide by 231 to determine gallons. 4.08 gallons.
What is the formula for finding the radius of a circle when you have the circumference?
Divide the circumference by 2*pi because 2*pi*radius = circumference
How do you find the radius of a circle with a circumferance of 70 inches?

How do you find the diameter with out the radius?
Divide the circumference by pi Or divide the area by pi and then take the square root of the value found.
What is the radius of a circle if you only know the perimeter?
Divide the perimiter, or circumference, by pi (3.1415), which is the diamter, then divide that by 2 to get the radius
How do you find the circumference if you have the radius?
First step is going to be to divide the circumference by Pi (about 3.1416). Next, divide by two to get the radius.
