Question

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

A. (4+4pi)ft^2
B. (4-pi)ft^2
C. (4+pi)ft^2
D. (4-4pi)ft^2

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

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

Answer 2

The area of the shaded region in terms of pi is (4-pi)ft^2

What is the area of the shaded portion?

The area of the shaded portion is the area of the square less the area of the ciricle.

Area of the square = length²

2² = 4

Area of a circle = πr²

Where :

• π = pi = 22/7
• R = radius = 2/2 = 1

π x 1² = π

Area of the shaded region = (4-pi)ft^2
