Answer:
474.5 ft ³
Step-by-step explanation:
<u>1) Find the volume of the cube</u>
where l is the side length
Plug in 9 ft as l
Therefore, the volume of the cube is 729 ft³.
<u>2) Find the volume of the cylinder</u>
where r is the radius of the base and h is the height of the cylinder
Plug in 3 ft as the radius and 9 as the height
Therefore, the volume of the cylinder is approximately 254.5 ft ³.
<u>3) Subtract the volume of the cylinder from the volume of the cube</u>
729 ft³ - 254.5 ft ³
= 474.5 ft ³
Therefore, the volume of the figure is 474.5 ft ³.

Answer:
The coordinates of B are (-8,25).
Step-by-step explanation:
Consider the completer question is " M(−2, 10) is the midpoint of AB. If A has coordinates (4, −5), what are the coordinates of B".
Let coordinates of B are (a,b).
Formula for midpoint:
Midpoint of A and B is
It is given that M(−2, 10) is the midpoint of AB.
On comparing both sides we get
Multiply both sides by 2.
Subtract 4 from both sides.
The value of a is 8.
Similarly,
Multiply both sides by 2.
Add 5 on both sides.
Therefore, the coordinates of B are (-8,25).
