What is the volume of a sphere if the radius is six

Volume of a sphere is 4/3 pir^2 so

r=6 so

4/3 pi 36=

4/3 times 36 (associative property of multiplication [a (bc) = (ab) c]) 144/3=48

48π square units is the answer

but if you want the numbers

π≈3.1415926535898 ...

so 48 times π≈150.796 square units but you teacher would only require 150.80 square units
