Answer:
Step-by-step explanation:
Use the midpoint formula to solve:
We know the midpoint and one set of coordinates, so filling those in:
Since the -7 is the x coordinate of the midpoint, we set the x part of the equation equal to -7 and solve for x, and then do the same for y. The 2 equations are:
and 
We solve each one of these to get the x and y coordinates of the other endpoint. In both cases, multiply both sides of the equations by 2 and then solve by either adding or subtracting.
-14 = x - 19 so
5 = x
16 = y + 30 so
-14 = y
The coordinates of the other endpoint are (5, -14)
the volume is 1/3 * height *area of the base (the circle) in cubic units
the area of the circle is pi*r²
wich gives us
1/3 * 11 * pi * 5²
rearrange
= 5² * 11 * 1/3 * pi
= 25*11*1/3*pi
= 275*1/3*pi
= 275/3 *pi
= (91 2/3)*pi
in cubic units
so your answer is the first option
Answer:
x = 1
Step-by-step explanation:
Subtract 3 from both sides
x+ 3 - 3 = 4 - 3
gives x=1
