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
This is a right triangle. If the triangle were laid down, on an end, a right angle would be visible.
Answer:
99
Step-by-step explanation:
=> 9801/99 = 99
Since we aren't told the length of the 3rd bar, focus solely on the lengths of the first 2 bars. Add together their lengths: 1.15 cm + 3.92 cm = 5.07 cm.
102/17 = 6
(6*2)+(17*2) = 46
Hope this helps! :)
