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
The radius is half the diameter.
Radius = Diameter/2.
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.
