Formula for area of a circle
Here a three ways to find the area of a circle (formulas):
Circle area formula in terms of radius
Circle area formula in terms of diameter
Circle area formula in terms of circumference
See below some definitions related to the formulas:
Circumference is the linear distance around the circle edge.
The radius of a circle is any of the line segments from its center to its perimeter. The radius is half the diameter or r = d.
The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. The diameter is twice the radius or d = 2·r.
The Greek letter π
π represents the number Pi which is defined as the ratio of the circumference of a circle to its diameter or π = C . For simplicity, you can use Pi = 3.14 or Pi = 3.1415. Pi is an irrational number. The first 100 digits of Pi are: 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679 ...
If you input the radius in centimeters, you will get the answer in square centimeters (cm²), if in inches, will get the answer in square inches (in²) and so on ...
Circumference is often misspelled as circunference.
