Step-by-step explanation:
the volume of :
cone = ⅓π.r².r= ⅓π.r³
cylinder = π.r²r= π.r³
Sphere = 4/3 π.r³
for r = 9 in =>
the volume of:
14. cone = ⅓.π.9³= ⅓π × 729 = 243π in³
15. cylinder = π.9³ = 729π in³
16. Sphere = 4/3 π.9³ = 972π in³
17. the volume ratio among cone, cylinder and Sphere is : ⅓ : 1 : 4/3 =
1 : 3 : 4
Answer:
1/78
Step-by-step explanation:
A standard die has 6 sides meaning 1/6
A standard deck has 52 cards and four 8 cards meaning 1/13
Answer:
I think it is C
Step-by-step explanation:
If I'm wrong try B
This solid object contains 8 sides.
The side that is facing you has a surface area:
The side exactly opposite this one has the same surface area - 2 sides with this surface area in total.
The bottom side has a surface area:
The side to your right has a surface area:
The side to your left has a surface area:
The side to your top left has a surface area:
The side beside the side to the top left has a surface area:
The side at the very top has a surface area:
Combined, the surface area is:
Therefore the answer is: C

14/24 * 100%
0.5833 * 100%
≈ 58.33%
