64 pi
Area = pi*322 = 3216.990877 or about 3217 square cm
64 pi square centimeters
Divide the diameter by 2, to get the radius. Then use the formula for the area of a circle:area = pi x radius squared
Area of a circle in square cm = pi*radius2
Area of circle: pi*8^2 = 64*pi square cm
64 pi
Area = pi*322 = 3216.990877 or about 3217 square cm
64 pi square centimeters
The area of a 3 cm circle is: 7.069 square cm
Radius of circle: square root of (324/pi) = 10.1554125 cm Circumference of circle: 2*pi*10.1554125 = 63.80833861 or 64 cm to the nearest integer
Divide the diameter by 2, to get the radius. Then use the formula for the area of a circle:area = pi x radius squared
The area of a circle with diameter 18.8 cm = the area of a circle with radius 9.4 cm = pi*r2 = 277.59 cm2, approx.The area of a circle with diameter 18.8 cm = the area of a circle with radius 9.4 cm = pi*r2 = 277.59 cm2, approx.The area of a circle with diameter 18.8 cm = the area of a circle with radius 9.4 cm = pi*r2 = 277.59 cm2, approx.The area of a circle with diameter 18.8 cm = the area of a circle with radius 9.4 cm = pi*r2 = 277.59 cm2, approx.
Area of a circle in square cm = pi*radius2
Area of a circle in square cm = pi*radius2
4 cm radius = Area of 50.26548 sq. cm.
A circle with a radius of 3 cm has an area of 28.27 square cm.
