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

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
