A(Circle)=Pi*Diameter^2
^2 = squared or to the 2nd power
circumference of a circle = pi * diameter.
The formula to find the circumference of a circle is C = πd, where d is the diameter. Using this formula, the circumference of a circle with a diameter of 18 in is C = π × 18 = 56.52 in.
Circumference of a circle = pi*diameter or 2*pi*radius
(pi)D
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
circumference of a circle = pi * diameter.
The formula to find the circumference of a circle is C = πd, where d is the diameter. Using this formula, the circumference of a circle with a diameter of 18 in is C = π × 18 = 56.52 in.
Circumference = (diameter) multiplied by (pi)
Circumference of a circle = pi*diameter or 2*pi*radius
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
the formula is: circumference= p*diameter
Well to find the radius it is diameter/2.
(pi)D
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
Circle's circumference = 2*pi*radius or diameter*pi
The formula is pi multiplied by the diameter
Area = Pi(d/2)2 where d = diameter
