Answer:
3 cm
Step-by-step explanation:
First, find the volume of the cone.
V = 
r²h
V =
(3.14)(9)(12)
V = 113.04
This means the sphere is also 113.04
Use the formula V = 
r³
113.04 =
(3.14)r³
113.04 = 4.19r³
26.98 = r³
3 ≈ r
Answer:
its 42.89
Step-by-step explanation:
V=1/3πr^2h
d=3.6 in.
r=1.8 in.
V=1/3×π×1.8^2×3
V≈10.1736 cubic inches. As a result, the volume of the funnel is 10.1736 cubic inches. Hope it help!
Answer:
12.6 hp
Step-by-step explanation:
Represent the input by n. 10.75 hp
