I knew there was a formula for this, but did not remember it and so had to look it up.  The formula is:

A = pi*r*(r + sqrt(h^2+r^2) )

Here, A = 3.14(4 ft)(4 ft + sqrt(36 + 16) = 140.9 square feet.

When in doubt about a formula, look it up!

sveticcg [70]

Answer:

540 megabytes

Step-by-step explanation:

We will first need to find out how much space a<em> singular song</em> will take up. We will do this by <em>the storage taken up (884) by the number of songs she has:</em>

884 / 221 = 4 mb taken up per song

Then we want to find out how many megabytes <em>135 of these songs take up</em>, so we will multiply the <em>mb taken up per song (4) by the number of songs we want to find (135)</em>:

4 x 135 = <em>540 megabytes</em>
