Question

2. How much extra snow would a child need to make a snowball with a diameter of 8

cm and increase its size to a snowball with a diameter of 12 cm?
​

Answer 1

62.8 cm²

Explanation:

First, you figure out the areas of both snowballs:

πr² = π4² = 3.14 × 16 = 50.24

πr² = π6² = 3.14 × 36 = 113.04

Then you subtract the two measurements:

113.04 - 50.24 = 62.8
