Answer:

Snow is needed to make the snowman is= 155.04 cubic feet

Explanation:

Given the bottom ball is 3 feet across.

The volume of snow to make the bottom ball=
(4)/(3) \pi r^3


=(4)/(3) \pi * 3^3 cubic feet

The middle ball is 2 feet across.

The volume of snow to make the middle ball=
(4)/(3) \pi r^3


=(4)/(3) \pi * 2^3cubic feet

The top ball is 1 feet across.

The volume of snow to make the top ball=
(4)/(3) \pi r^3


=(4)/(3) \pi * 1^3 cubic feet

Snow is needed to make the snowman is

(
(4)/(3) \pi * 3^3+(4)/(3) \pi * 2^3+(4)/(3) \pi * 1^3) cubic feet


= (4)/(3) \pi (27+8+1) cubic feet


=(148)/(3) \pi cubic feet

=155.04 cubic feet
