Hello!
First you have to find the volume of the cylinder
To find the volume of a cylinder you use the equation
V is volume
r is radius
h is height
Put in the values you know and 3.14 for pi
Square the number
V = 3.14 * 9 * 7
Multiply
V = 197.82
------------------------------------------------------------------------------------------------------
Next you find the volume of the sphere
To find the volume of a sphere you use the equation
V is volume
r is radius
Put in the values you know and 3.14 for pi
Cube the number
Multiply
V = 113.04
------------------------------------------------------------------------------------------------------
Finally you subtract the two volumes from each other
197.82 - 113.04 = 84.78
------------------------------------------------------------------------------------------------------
The answer is C)84.78
Hope this helps!

First step is to plot all the given coordinates in the xy plane.
Notice that after plotting the points A, B, C and D, we have got the figure ABCD is a trapezium with bases AD = 4 units, BC = 6 units and height: DE= 5 units.
Formula to find the area of trapezium is:
Area =
=
=
= 5 * 5
= 25 square units.
So, third choice is correct.
Hope this helps you!
