Explain mathematic equation

The formula for radius to area is: A = πr2 A = π r 2 How To Find Radius From Diameter If you know the diameter of a circle, you can find its radius by dividing the diameter by 2 2: r = d 2 r = d 2 This is the simplest formula you can use to

Circle Calculator Choose a Calculation radius r = Let pi π = Units Significant Figures Answer: radius r = 12 in diameter d = 24 in circumference C = 75.3982237 in area A = 452.389342 in 2 In Terms of Pi π circumference C = 24 π in area A
