Radius of a circle = diameter/2
The radius is one half of the diameter. If the diameter is 20, the diameter is 10.
radius is half diameter...so divide diameter by 2!!!
you have multiplythe radius by 2 to get the diameter
The formula to calculate radius is Pi x Diameter. So, if the radius is 7, the diameter is 14. Then, do 14 x pi (3.14) and your circumference will be 43.96
To find the diameter of a circle with a given area, you first need to calculate the radius using the formula for the area of a circle: A = πr^2. Given that the area is 314 cm^2, you can rearrange the formula to solve for the radius, which would be √(A/π). Plugging in the area, you get √(314/π) ≈ 10 cm. Finally, to find the diameter, you double the radius, resulting in a diameter of approximately 20 cm.
To calculate the radius when the diameter is given, simply divide the diameter by 2. The formula is: radius = diameter / 2. For example, if the diameter is 10 units, the radius would be 10 / 2 = 5 units.
Circumference = diameter*pi
well if the radius is given then the diameter is : d=2r. as for in a circle the diameter is : d=2(pi)r pi=3.14
Double the Radius to Calculate the Diameter.
diameter = 2 * radius
the radius is half the diameter
Radius = Diameter/2.
The radius is half the diameter.
The radius is half of the diameter. If the diameter is 48, you can calculate the radius by dividing the diameter by 2. Therefore, the radius is 48 ÷ 2 = 24.
I guess you mean:"How do you find the radius if you are given the diameter?"You take the diameter and divide it by 2.
divide diameter by 2 = radius
The radius is one half of the diameter. If the diameter is 20, the diameter is 10.
