Answer:
V = 3078.76 in³
Step-by-step explanation:
To find the volume of a cylinder, use this formula:
V = πr²h
- V = volume
- r = radius
- h = height
Plug in the values you know.
V = π(7)²(20)
First let's evaluate the exponent.
7² = 49
V = π(49)(20)
Now let's multiply.
49 • π = 153.938
153.938 • 20 ≈ 3078.76
V = 3078.76 in³
This is your answer.
Hope this helps!

Answer:
the cost of the three new CDs is $44.28
Step-by-step explanation:
Here in this question, we are interested in calculating the cost of 3 new CDs cost.
From the question, we already know the cost of one. The cost of three would be 3 multiplied by the cost of one.
The cost of the three excluding the sales tax = $13.79 * 3 = $41.37
The sales tax for the three pieces = 3 * $0.97 = $2.91
The cost of the three CDs including the sales tax = $41.37 + $2.91 = $44.28
Here is something you can do on your own, if you have a pencil and
a scrap of paper:
-- Draw a triangle. It has 3 sides. Count its angles.
-- Draw something with 4 sides. Count its angles.
-- Draw something with 5 sides. Count its angles.
-- Draw anything with 6 sides. Count its angles.
This doesn't PROVE anything, because you haven't tried polygons with
every possible number of sides, so there may be an exception to the rule.
But by trying only these few cases, you'll probably begin to notice a rule.
If you can't find a pencil and a scrap of paper, you can probably perform
this same experiment using a brain.
