Question

3. Find the area of the shaded region. Leave your answer in terms of pi. (1 point)

Answer 1

ANSWER

B.

$(4 - \pi) {ft}^{2}$

EXPLANATION

The area of the square is

${l}^{2}$

The length of the square is

$l = 2ft$

The area of the square is

$= {2}^{2} = 4 {ft}^{2}$

Area of the circle is

$= \pi \: {r}^{2}$

The radius of the circle is

$r = \frac{2}{2} = 1ft$

Area of circle is

$= \pi \: \times {1}^{2} = \pi {ft}^{2}$

The area of the shaded region is

$= (4 - \pi) {ft}^{2}$
