Area = pi * r2 Circumference = 2 * pi * r Pi = 3.141592 r = square root of Area/pi Cir then = 2 * pi * (square root of Area/pi)
pi*radius2 = area radius = square root of (area/pi) circumference = 2*pi*radius
Radius = square root of (area/pi) Circumference = 2*pi*radius
Divide the area by pi, which gives you the square of the radius. Take the square root and multiply by 2 pi and you have the circumference.
Square root (Area/pi) to get the radius Then 2xRadiusxPi= Circumference
What do you have? The area of the circle or the circumference? Area: divide the area by pi, then square root it Circumference: divide the circumference by 2 then divide it by pi
pi is the square root of ten ---------- Incorrect. Pi is the mathematical ratio between the circumference and the diameter of a circle. Coincidentally, it is also the ratio between the area of a circle and the square of its radius. The square root to 10 is ~3.16227766, while Pi is ~3.1415926535897932
Divide the circumference by pi Or divide the area by pi and then take the square root of the value found.
