A cone-shaped chemical tank is 12 feet high and has a diameter of 45 feet. The tank is half full. How many cubic feet of liquid is in the tank?

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

equation to find volume of a cone

 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

if it is easy u should do it but...

its 60-10+x why, because she bought the dress with $60 and she received $10 dollars back. We don't know the variable.
