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>

Cas walks 3/5 miles in 24 min at a steady pace, how long does it take him to walk 2 miles?
san4es73 [151]
Your answer is 80 mins, or an hour and 20 mins. You simply turn that fraction to a decimal by diving 3 with 5. This should turn out to be 0.6. Then you multiply the 24 mins with the 2 miles and it turns out to be 48. After this, you divide 48 by 0.6 and you get 80.
