Alan is correct....let's put this one "in the tank."

The volume of the tank is given by

V = (4/3)pi(r³)   where r is the radius

So we have

V = (4/3)pi(7.7m)³  =  about 1912.320958 m³

And 1 m³ = 1000L

So  1912.320958 x 1000 = about 1,912,321 L

LOL!!!!

I believe these points are meant to be rotated around the origin....

1. For the first one....C is at (2,2)......rotating a point in the first quadrant 90 degrees clockwise reverses the coordinates and changes the sign on the original x coordinate.....so....(2, 2) becomes (2, -2)......

2. Rotating a point in the second quadrant 90 degrees clockwise reverses the coordinates and changes the sign on the original x coordinate . So, B= (-1,4) and B' = (4, 1)

3. Here, we're just doing the opposite of what we did in (2). E = (3, 2), so E' = (-2, 3)

4. Rotating a point in the second quadrant 90 degrees counter-clockwise reverses the coordinates and changes the sign on the  original y coordinate. So B = (-1, 4) and B' = (-4, -1).

-16 -(6x-4)=6   add 16 to both sides

-(6x - 4) = 22    distribute the negative across the terms in the parentheses

-6x + 4 = 22      subtract 4 from both sides

-6x = 18           divide both sides by -6

x = -3

Maybe you're just dyslexic.........

10/18=?/100       cross-multiply

10 x 100 = 18 x ?     divide both sides by 18

10 x 100 / 18 = ? = about 55.55

Thanks for those resources, Melody....this is something that is easier shown rather than just explained  !!!!

Here's a graph representing geno's set up..........The station is located at B....BC is the distance the plane is from the station intially and AC is the height of the plane aboive rhe station.
