The area of a circle with a radius of 7 cm is: 153.9 cm2
3850m is the area of the a circle whose radius of 7meaters
Area of circle = pi x radius x radius where pi = 3.14159 If radius = 6 cm then Area = 3.14159 x 6 x 6 sq cm = 113.097 sq cm
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)
approximately 7 centimeters.
Circumference is 2π times the radius. So, for 14π the radius is 7. Area is πr2, so the area of a circle with radius 7 is 72π, or 49π (153.93).
circumference = 2*pi*7* centimeters
Area of any circle = pi*radius squared
The relationship between the radius and area of a circle is as follows: Area of circle = 3.14 x Radius x Radius or 22/7 x Radius x Radius
The area is 154 cm2
Area = 153.94 in2
