Given the information of the conical hat

diameter of 16 inches => Radius = 8 inches
height of 9 inches

=> the slant height of the hat is (use Pythagorean Theorem)

$s^{2}$ = $r^{2} + h^{2}$

<=> $s^{2}$ = $8^{2} + 9^{2}$

<=> s = $\sqrt{145}$

The area (without the base area) of tissue paper will she need to make one hat is:

SA = πrs in2

<=> SA = π*8* $\sqrt{145}$ in2

<=> SA =8 $\sqrt{145}$ π

=> the total tissue paper will she need for 21 hats is:

SA*21

= 8 $\sqrt{145}$ π*21

= 6352,18 in 2

blondinia [14]

Answer:
Store 1 has the better deal.

Explanation:
If you divide the amount the prices by the amount of paper towel roll, you would see store 1 has the better deal.

3.60 divided by 12 = 0.30
3.50 divided by 10 = 0.35

As you can see, store 1 is less expensive than store 2. Therefore, store 1 is the better deal.
