4. Find the area of the<br> shaded region.

lozanna [386]

Diameter of the circle in the middle = 8 ft

Radius of the circle in the middle :

$=\tt \: \frac{Diameter }{2}$

$=\tt \frac{8}{2}$

$=\tt 4 \: ft$

Thus, the radius of the circle in the middle = 4 ft

Area of the entire circle :

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

$= \tt3.14 \times 4 + 6 \times 4 + 6$

$= \tt3.14 \times 10 \times 10$

$=\tt 3.14 \times 100$

$\color{plum} = \tt314 \: ft$

Thus, the area of the entire circle = 314 ft

Area of the circle in the middle :

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

$=\tt 3.14 \times 4 \times 4$

$= \tt3.14 \times 16$

$\color{plum} =\tt 50.24 \: ft$

Thus, the area of the circle in the middle = 50.24 ft

Area of the shaded portion :

= Total area of the figure - Area of the circle in middle

$=\tt 314 - 50.24$

$\color{plum} =\tt 263.76 \: ft$

▪︎Therefore, the area of the shaded portion = <u>263.76 ft</u>

Kay [80]

Step-by-step explanation:

Line AB = sqrt18 = 4.24

Line BC = sqrt10 = 3.16

Line AC = 4

Since the triangle cannot be isosceles or equilateral, the best option here is scalene.
