Answer 1

3.

`volume \ of \ cone = (1)/(3)\pi r^2h = (1)/(3)*3.14*6*6*15 = 3.14*36*5 = 565.2cm^3`

4.

`volume \ of \ cone = (1)/(3)\pi r^2 h = (1)/(3) *3.14* 12*12*20 = 3.14*12*4*20 = 3014.4cm^3`

5.

`volume \ of \ sphere = (4)/(3) \pi r^3 = (4)/(3)*3.14 * 3*3*3* = 4*3.14*9 = 113.0cm^3`

6.

`diameter = 13cm\\\\radius = 6.5cm\\\\volume \ of \ sphere = (4)/(3) \pi r^3= (4)/(3) *3.14*6.5*6.5*6.5 = 1149.8cm^3`
