So firstly, let's start with the x-coordinates. Since we know the midpoint's x-coordinate and point A's x-coordinate, we can solve for point B's x-coordinate as such:
Next, do the same thing except solve for the y-coordinate and using point A's y-coordinate and the midpoint's y-coordinate:
<u>Putting it together, point B's coordinates are (2,4).</u>
Answer:
4 pitchers
Step-by-step explanation:
we know that
The volume of a cylinder is equal to
step 1
Find the volume of the cylinder with height 9 inches and radius r
substitute the given values
step 2
Find the volume of the cylinder with height 9 inches and radius 2r
substitute the given values
step 3
we know that
The volume of the cylinder 1 can fill a certain pitcher,
so
The volume of the pitcher is the same that the volume of cylinder 1
therefore
the number of pitchers that can be filled by the second cylinder is equal to divide the volume of the second cylinder by the volume of the first cylinder
