You will first need the formula for finding area of a cricle:
A = Pi • r2
Now that we know the formula we need, let's plug in our numbers.
A = 3.14 • (5.3)2 cm
A = 3.14 • 28.1 cm
A = 88.2 cm
So a circle with a radius of 5.3 cm has an approximate area of 88.2 centimeters.
Area = pi*4.12 = 52.81017251 or about 53 square cm
Area of a circle in square cm = pi*radius squared
A circle with a radius of 2 cm has an area of 12.57 square cm.
A circle with a radius of 25 cm has an area of 1,963.5 square cm.
A circle with a radius of 19 cm has an area of 1,134.11 square cm.
Area = pi*4.12 = 52.81017251 or about 53 square cm
Area of a circle in square cm = pi*radius squared
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.
A circle with a radius of 19 cm has an area of 1,134.11 square cm.
A circle with a radius of 2 cm has an area of 12.57 square cm.
A circle with a radius of 25 cm has an area of 1,963.5 square cm.
A circle with a radius of 4 cm has an area of 50.27 square cm.
A circle with a radius of 2.7 cm has an area of 22.9 square cm.
A circle with a radius of 8.2 cm has an area of 211.24 square cm.
The area of a circle with a 14 cm radius is: 615.8 cm2
The area of a circle with a radius of 15 cm is: 706.9 cm2
