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:
No
Step-by-step explanation:
4/6 is also equal to 8/12
9/12 is bigger than 8/12
Answer:
x = 17
Step-by-step explanation:
Since the triangles are similar then corresponding angles are congruent.
∠ I = ∠P ← substitute values and solve for x
3x + 4 = 72 - x ( add x to both sides )
4x + 4 = 72 ( subtract 4 from both sides )
4x = 68 ( divide both sides by 4 )
x = 17
1 hour = 70 miles
3 hours = 70 x 3
= 210 miles
The answer would be 210 miles.
