I dont know the answer, its hard

Answer 1

Answer:

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

Step-by-step explanation:

Given the bottom ball is 3 feet across.

The volume of snow to make the bottom ball= $\frac{4}{3} \pi r^3$

                                                                            $=\frac{4}{3} \pi \times 3^3$  cubic feet

The middle ball is 2 feet across.

The volume of snow to make the middle ball= $\frac{4}{3} \pi r^3$

                                                                          $=\frac{4}{3} \pi \times 2^3$cubic feet

The top ball is 1 feet across.

The volume of snow to make the top ball= $\frac{4}{3} \pi r^3$

                                                                     $=\frac{4}{3} \pi \times 1^3$  cubic feet

Snow is needed to make the snowman is

($\frac{4}{3} \pi \times 3^3+\frac{4}{3} \pi \times 2^3+\frac{4}{3} \pi \times 1^3$)   cubic feet

$= \frac{4}{3} \pi (27+8+1)$ cubic feet

$=\frac{148}{3} \pi$ cubic feet

=155.04 cubic feet
