well, technically since the formula for circumference is c=2pir, technically r=c/2pi (otherwise stated as radius equals circumference divided by two pi).

Formula and result of area of circle?
The formula for the area of a circle is: Area = (pi) x (Radius)2 . When you know the radius of the circle and you use it to calculate the area of the circle, the result will be equal to (pi) x (Radius)2 .
Why do you use the radius in the formula of finding the area of a circle?
Area of circle = pi*(radius)2
What the formula in circle?
Area of a circle = pi*radius squared Circumference of a circle = 2*pi*radius or diameter*pi
What is formula for radius o a circle?
radius = 1/2 diameter
What is the formula for finding perimeter of a circle?
The formula for the circumference of a circle is pi * diameter or (2 radius.)
Formula of circle?
The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.
What is the formula for area for circle?
The formula for the area of a circle is πr2, written in verbal form as: "The value Pi times the radius of the circle squared", where r is the radius (half of the diameter, or the distance from the center to any point on the outer edge of the circle) of the circle, and π equals about 3.1415.
Formula for radius of circle?
radius = diameter/2
Formula for radius of a circle?
radius = diameter/2.
What is the formula for the diameter or a circle?
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
What is Pi R Squared?
The formula to get the area of a circle ("R" being the radius of the circle). Radius means the distance from the center of the circle to the edge.It means pi times radius squared which is the formula for finding the area of a circle.
How do you write the formula to a circle in the form x?
(x - A)2 + (y - B)2 = C2 (A,B) is the center of the circle. 'C' is the circle's radius.
Formula and result of area of circle?
The formula for the area of a circle is: Area = (pi) x (Radius)2 . When you know the radius of the circle and you use it to calculate the area of the circle, the result will be equal to (pi) x (Radius)2 .
Why do you use the radius in the formula of finding the area of a circle?
Area of circle = pi*(radius)2
What is formula for the area of a circle?
the formula for the area of a circle is 3.14 x radius squared
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
What is the formula for a circle radius r?
Area of a circle = pi*radius2 Circumference of a circle = 2*pi*radius or diameter*pi Diameter of a circle = 2*radius
