Answer:

y-coordinate= 4

Step-by-step explanation:

y+2= -3( x-4) Solve for y

y= -3( x-4) -2

y= -3x +12 -2

y= -3x +10

Now in the given ( _, -2) x=-2

Substitute x= -2 to find the matching y value.

y= -3x +10

y= -3(2) +10

y= -6 +10

y=4

Given y+2= -3( x-4) the missing blank is (4, -2)

8th grade geometry part 3, please explain the steps :)))

Answer: Volume = 97.6

Step-by-step explanation:

Volume of the cone first

V = 1/3 h π r²

<u>h = 0.7</u>

<u>r = 2</u>

V = 1/3 × 0.7 × 2² × 3.14

V = 1/3 × 0.7 × 4 × 3.14

V = 1/3 × 8.792

V = 2.93

Then find the volume of the cylinder if the cone was there.

V = π r² h

<u>r = 2</u>

<u>h = 8 </u>

V = 3.14 × 2² × 8

V = 3.14 × 4 × 8

V = 3.14 × 32

V = 100.48

Now you subtract the volume of the cone from the cylinder.

100.48 - 2.93 = 97.55

Rounded to the nearest tenth is 97.6

Hope this was helpful, I know it is a lot to look at but I tried my best.

Also, can I get brainliest? I worked really hard on this.

Answer:

502.4 square inches

Step-by-step explanation:

To find the area of the shaded region, you first need to find the area of the smaller circle with diameter 12, and then subtract that from the area of the larger circle. Since the diameter of a circle is twice the radius, the radius of the smaller circle is 6, and its area is therefore:

\pi \cdot 6^2 = 3.14\cdot 36=113.04

The area of the larger circle, which has radius 6+8=14, is:

\pi \cdot 14^2= 3.14 \cdot 196=615.44

Subtracting the area of the smaller circle from his, you get an area of 502.4 square inches for the shaded area. Hope this helps!
