Question

The largest possible circle is cut out of a square whose side length is 12 feet. What will be the approximate area, in square feet, of the remaining board?

Answer 1

Explanation:

30

Answer 2

31 ft²

Explanation:

(1) Area of square

A = l²

A = 12²

A = 144 ft²

=====

(2) Area of circle

A = πr²

A = π × 6²

A = π × 36

A = 113 ft²

=====

(3) Remaining area

A = 144 – 113

A = 31 ft²

The area of the remaining board is 31 ft².
