Question

A circular skating rink has an area of about 417 square feet. The town recreation committee wants to make the rink three times as large. If the committee decides to triple the radius, what is the approximate area of the new rink?

Answer 1

3753 square feet

Explanation:

The area is proportional to the square of the radius. If the radius is tripled, the area is increased by a factor of 3² = 9.

9 × 417 ft² = 3753 ft²

The approximate area of the new rink will be 3753 ft².
