Alicia is sewing a rectangle bedspread that measures 72 inches by 60 inches. The bedspread is red with a gold circle 18 inches in diameter in the center. To the nearest square inch, what is the area of the bedspread that is red?

Respuesta :

Answer:

[tex]4,066\ in^{2}[/tex]

Step-by-step explanation:

we know that

The area of the bedspread that is red is equal to the area of rectangle minus the area of the circle

step 1

Find the area of rectangle

The area is equal to

[tex]A=72*60=4,320\ in^{2}[/tex]

step 2

Find the area of the circle

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=18/2=9\ in[/tex] ----> the radius is half the diameter

assume

[tex]\pi=3.14[/tex]

substitute

[tex]A=(3.14)(9)^{2}[/tex]

[tex]A=254.34\ in^{2}[/tex]

step 3

Find the area of the bedspread that is red

Find the difference of the areas

[tex]4,320\ in^{2}-254.34\ in^{2}=4,066\ in^{2}[/tex]
