An oil storage tank is a cylinder 30 feet high. the base of the tank is a circle with a diameter of 50 feet. when full, how many gallons are in the tank? 1 gallon equals approximately 0.13 cubic feet.

Answer with Step-by-step explanation:

An oil storage tank is a cylinder 30 feet high.

The base of the tank is a circle with a diameter of 50 feet.

The water in tank will be equal to the volume of the tank.

We know that volume of cylinder is given by:

V=πr²h

where r is the radius and h is the height

Here, r=25 feet (since radius=diameter/2)

and h=30 feet

Volume=3.14×25×25×30

            =58875 cubic feet

1 gallon=0.13 cubic feet

1 cubic feet=1/0.13 gallon

58875 cubic feet=58875/0.13 gallons

                            = 452884.62 gallons

Hence, water in tank equals:

452884.62 gallons

ha!

i just did this!

18. g

20. h 30 degree turn.

21. d 90 degree angles

and also 19 is a. a sphere not a cirlcle

hope i !

pls mark me brainiest
