Answer:
a) 1680
<em>The number of ways to listen to four CDs from a selection of 8 CDs = 1680</em>
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given data the number of CD' s n = 8
<em>We have to selected '4' CD' s from total '8' CD's</em>
<em>By using permutations </em>
<em>The number of ways to listen to four CDs from a selection of 8 CDs.</em>
<em> = </em>
<em> </em>
<em> we know that </em>
<em>The number of ways to listen to four CDs from a selection of 8 CDs = 1680</em>
A: {-4, -2 -1, 2}<br>
B: {-4, 4}<br>
C: {-3, -2, 0, 2}<br>
D: {-4, -2, -1, 0, -2}

Answer:this is soooo compli
Step-by-step explanation:
The volume of a cylinder that has a radius of 6 inches and is 15 inches tall is 540 π cubic inches
<h3>How to calculate the volume of a cylinder?</h3>
The formula for calculating the volume of cylinder is expressed as:
V = πr²h
where
r is the radius
h isthe height
Given the following parameters
h = 15in
r = 6in
substitute
V = 6^2 * 15π
V = 540 π cubic inches
Hence the volume of a cylinder that has a radius of 6 inches and is 15 inches tall is 540 π cubic inches
