Divide the circumference by (2 x pi) to get the radius. Then use the formula for the area of the circle.
To find the area of a circle knowing only the circumference, you can use the formula A = (C^2) / (4π), where A is the area and C is the circumference. Square the circumference, then divide it by 4π to get the area.
if it is the radius you can find area or circumference
The area of a circle with radius r is pi*r*r and its circumference is 2*pi*r Use the first to find r and then use that value of r in the second to find the circumference.
this concept is used by engineers. as they have to design buildings.
The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.
Divide the circumference by (2 x pi) to get the radius. Then use the formula for the area of the circle.
To find the area of a circle knowing only the circumference, you can use the formula A = (C^2) / (4π), where A is the area and C is the circumference. Square the circumference, then divide it by 4π to get the area.
Circumference = 2*radius Area = 2*pi*radius2 Area = 2*pi*(circumference/2)2
Circumference is what you use when finding the area of a circle.
The area of a circle with a circumference of 9.42 inches is: 7.06 square inches.
if it is the radius you can find area or circumference
Suggestion: Divide the circumference by (2 x pi) to get the radius. Then use the standard formula for the area of a circle.
The area of a circle with radius r is pi*r*r and its circumference is 2*pi*r Use the first to find r and then use that value of r in the second to find the circumference.
this concept is used by engineers. as they have to design buildings.
you use pi to calculate the area or circumference of a circle
They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
