Answer 2

For 11. Find the distance between A and B using the distance formula. I assume you learned that?
Then since B is the midpoint, the distance from A to B is the same as the distance from B to C.

12. Use the distance formula. (Or the pythagorean theorem).

13. Area of a circle is radius^2 * pi

Answer 3

Boy there's a lot of people!

Answer 4

Also can I get a medal for nothing? I mean the doge meme got one.

Answer 5

Lol.

Answer 6

I didn't know it would get a medal.

Answer 7

Someone just medal me. :/

Answer 8

11) The distance from the midpoint (B) and the endpoint (A) is 7 units, as the x is the same for both, so you only deal with the y values. The distance from A to B is also the same as the distance from B to C, as it's a midpoint, so it would be 7 units in the direction from A to B, or right, which would just be -8+7 which is -1, so C would be (5,-1)

12) Here, the distance formula should be applied (sqrt((x2-x1)^2+(y2-y1)^2)). Plugging in your values, you would get sqrt((12-(-8))^2+(6-18)^2), which simplifies to sqrt(544) or 4*sqrt(34)

13) Area of a circle is pi*r^2. r=d/2, which is 4 in. in this case. A=pi*4^2=pi*16=50.3 in.
