How Do You Work Out The Area Of A Circle If You Know The Radius To work out the area of a circle Find the value of the radius If the diameter is given this must be halved Substitute the value of the radius into the formula for the area of a circle
The formula to calculate the area of a circle using radius is as follows Area of a circle 215 r 2 And to calculate the area of a circle using diameter use the following equation Area of a circle 215 d 2 2 where is approximately equal to 3 14 It doesn t matter whether you want to find the area of a circle using diameter or Area of a circle is the region occupied by the circle in a two dimensional plane It can be determined easily using a formula A r2 Pi r squared where r is the radius of the circle The unit of area is the square unit such as m2 cm2 etc
