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
Answer:

Answer:
100°= angle b(VERTICAL OPPOSITE ANGLE)
100°+x°=180°[co interior angle]
x=180°-100°
x=80°
Answer:
-3x+12-9x+8=-3(4x-7)
-3x+12-9x+8=-12x+21
-12x+21=-12x+21
21=21
infinitely many solutions
hope this helps
have a good day :)
