Area = Pi(r)2 - A circle with a radius of 12 centimeters has an area of 452.39 square centimeters.
The area of a circle with a radius of nine centimeters is: 254.5 cm2
A circle with a radius of 18 centimeters has an area of 1017.88 square centimeters.
Area of a circle = (pi) x (radius)2Radius = 1/2 of the diameterArea of this particular circle = (pi) x (7)2 = 49 pi = 153.938 square centimeters (rounded)
Use the formula for the area of a circle: A = pi x r2, where "r" is the radius.
The radius of a circle whose area is 3.14 square centimeters is: 1 cm
For a radius of 5 centimeters the area are 78.53981633974483 square centimeters.
Area = Pi(r)2 - A circle with a radius of 12 centimeters has an area of 452.39 square centimeters.

A circle that has a radius of 4.6 centimeters has an area of 66.5 square centimeters.
The area of a circle with a radius of nine centimeters is: 254.5 cm2
The radius are 7 centimeters and the area are 153.93804002589985 square centimeters.
Area = Pi(r)2 - A circle with a radius of 4.6 centimeters has an area of 66.48 square centimeters.
A circle with a radius of 18 centimeters has an area of 1017.88 square centimeters.
Radius is x2 so area is x4.
Area = pi*r2Area = pi(5.29 cm)2= 87.9 cm2=========
Radius: square root of (1256/pi) = 20 cm rounded to nearest integer
