Answer:
Jess is 26, Cece is 29
Step-by-step explanation:
r = d/2
r = 15.6/2
r = 7.8 in.
thus the radius of the right circular cone is 7.8
v = 1/3(3.14)(7.8)^2(12.4)
v= 1/3(3.14)(60.84)(12.4)
v= 2368.866/3
v = 789.622
thus the volume of the right come is 789.622 cubic inches
Answer:
5.8
Step-by-step explanation:
Answer:
≈ 32°
Step-by-step explanation:
Distance between buildings= 91 m
Elevation difference= 192 m- 136 m= 56 m
Right triangle ΔABC is formed by connecting 3 points, see attached
∠C is one to be calculated
tan C=AB/AC= 56/91
tan C= 0.62
∠C ≈ 32°
-------------------
<em>∠B = (90°-32°)= 58° in case I misread which angle to be found</em>
