Answer:
Step-by-step explanation:
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 =
The area (without the base area) of tissue paper will she need to make one hat is:
SA = πrs in2
<=> SA = π*8* in2
<=> SA =8 π
=> the total tissue paper will she need for 21 hats is:
SA*21
= 8 π*21
= 6352,18 in 2
