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!
Answer:
The answer is 11/14 ft^2 or pi/4 ft^2
Step-by-step explanation:
The area of the sector bounded by that angle measure will be the area of the circle divided by 4
Area of the circle is;
pi * r^2
so the area here is;
22/7 * 1 * 1 = 22/7
divide this by 4
= 22/28 = 11/14 ft^2
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!
