What you're looking for here is the surface area of the sides of the glasses (what the koozies will cover). This is also what the amount represents.

The surface area of the sides is equal to the perimeter of the base times the height of the cylinder. It makes sense logically because the sides are basically the perimeter of the base, raised all the way up along the cylinder.

SA = perimeter x height
SA = pi x diameter x height
<span>SA = 3.14 x 3in x 4in
</span>SA = 37.68 in^2

She will use <span>37.68 square inches of fabric.</span>

Answer:

  about 520,000

Step-by-step explanation:

Following directions, we evaluate the equation by putting the value where the variable is and doing the arithmetic.

__

The value of x will be the number of days between May 26 and May 12. That value is ...

  x = 26 -12 = 14

Then the number of mosquitos is estimated to be ...

  y = 230,000(1.06^14) ≈  520,008

About 520,000 mosquitos will inhabit the city on May 26.

_____

<em>Additional comment</em>

Typically, an "estimate" is one or two significant figures. So, 520,000 is a reasonable estimate. 520,008 has more precsision than can be justified.
