Useful Math

Pi π
3.1416
Circumference of circle (or perimeter)
Pi*d   or    Pi*2*r where d=diameter   r=radius
Area of circle (or square footage)
Pi*r*r = (πr2)
Area of Sphere (or skin or roofing)
4*Pi*r*r =(4πr2) for hemisphere 2*Pi*r*r = (2πr2)
Volume of Sphere (or interior cubic footage used for calculating HVAC)
4/3 * Pi *r*r*r (4πr3/3)
for hemisphere = 2/3 * Pi *r*r*r = (2πr3/3)
note: by doubling the diameter of a sphere, the surface area is increased by a factor of 4; the volume is increased by a factor of 8
