1.a sphere with a radius of three units

 
By definition, the volume of a sphere is:
 V = ( \frac{4}{3} ) (\pi) (r ^ 3)

 Substituting values we have:
 V=(\frac{4}{3})(\pi)(3^3)
 Rewriting we have:
 V = (4) (\pi) (3 ^ 2)

V = (4) (\pi) (9)

V = 36\pi

 2.a cone with a diameter of twelve units and a height of three units
 
 By definition, the volume of a cone is given by:
 V =  \frac{1}{3}  (\pi) (r ^ 2) (h)

 Substituting values we have:
 V =  \frac{1}{3} (\pi) ((\frac{12}{2}) ^ 2) (3)

 Rewriting we have:
 V = (\pi) (6 ^ 2)

V = 36\pi
