formulae for a sphere

[surface] area = 4 * π * r^2
volume = (4/3) * π * r^3
circumference (perimeter) = 2 * π * r

where "r" is the radius

Volume of sphere= 4/3 (pi)r3
V = 4/3 (pi)r3
Surface area of sphere = 4(pi)r2
S = 4(pi)r2
Perimeter = 2(pi)r

area
triangle =1/2 base * height
trapezoid= Base1 * Base2 * height 1/2
circle = 3.14 r square
rectangle = base times height,,,,,,,,,,,,,,,,,,,,,,,,,
