Point m is located at 4,-2 what is located 2 units for point m

eimsori [14]

Answer:

None

Step-by-step explanation:

Given

$m = (4,-2)$

Required

Point 2 units from m

There are 4 possible points 2 units from m and they are:

$m' = (4+2,-2) = (6,-2)$

$m" = (4,-2+2) = (4,0)$

$m'''= (4-2,-2) = (2,-2)$

$m'''' = (4,-2-2) = (4,-4)$

From the graph, we have:

$A = (4,2)$

$B = (-4,2)$

$C = (2,-3)$

None of the points is 2 units from m

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>
