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
The two x-values to your equation is
x=2 and x=-0.5
We can’t see the picture it shows a black screen!!
So all you need to do in order to find the sum is add so 185+66=251
