Area of a circle: pi*radius^2 Circumference of a circle: 2*pi*radius or diameter*pi Surface area of a sphere: 4*pi*radius^2
Pi is approximately equal to 3.141592652389793238462.
It is a decimal
Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius2 Volume of a sphere = 4/3*pi*radius3 Surface area of a sphere = 4*pi*radius2 Total surface area of a cylinder = (2*pi*radius2)+(2*pi*radius*height)
