Answer:

a. 14726.216ft^{3}

b. 110446.62gal

Step-by-step explanation:

I attach the diagram of the new water tank.

a. In order to find the volume of the tank in cubic feet, we will need to calculate the volume of a cylinder. We know that its base measures 25ft and its height is 30ft.

The volume ''V'' of a cylinder is :

V=(\frac{\pi D^{2}}{4}).(H)

Where ''D'' is the diameter of the base and ''H'' is the height of the cylinder.

If we replace all the data in the equation :

V=\frac{\pi .(25ft)^{2}}{4}.(30ft)=14726.216ft^{3}

We found out that the volume of the tank in cubic feet is 14726.216ft^{3}

b. We know that 1 cubic foot of water is equal to 7.5 gallons. To find the amount of gallons that the new tank can hold, we need to do an unit conversion.

This equivalence is given to us :

1ft^{3}=7.5gal ⇒ Using the equivalence ⇒

(14726.216ft^{3}).(\frac{7.5gal}{1ft^{3}})=110446.62gal

Finally, the new tank will hold 110446.62gal of water.
