many cubic feet of liquid is in the tank?

Sagot :

Answer:

V= 3180.87

Step-by-step explanation:

to know radius=

radius*2= diameter

reverse it to find radius

45 feet= radius*2

45 ÷2= radius = 22.5

[tex]V= \pi r^2\frac{h}{3}[/tex] equation to find volume of a cone

[tex]V=\pi 22.5^2\frac{12}{3}[/tex]  12 is from height

V≈ 6361.72512

Rounded V= 6361.73

Tank is half full so divide by 2

6361.73 ÷ 2= 3180.865

Rounded: V= 3180.87
