Let $A = (-3,8)$ and $B = (-5,4)$. The midpoint of $\overline{AB}$ is $\left( \frac{(-3) + (-5)}{2}, \frac{8 + 4}{2} \right) = (-4,6)$.
The slope of $\overline{AB}$ is $\frac{8 - 4}{(-3) - (-5)} = 2$, so the slope of the perpendicular bisector of $\overline{AB}$ is $-\frac{1}{2}$. Therefore, the equation of the perpendicular bisector is given by
Volume=legntht imes widht time height volume=11 and 3/5 times 9 times 12 and 1/2 volue=11 and 6/10 times 9 times 12 and 5/10 volume=11.6 times 9 times 12.5 volume=1305 m^3
