GaryK [48]
$8.50 because if he worked 40 hours a week you would multiple that by 52 because there are 52 weeks in a year. From there you would take the total he made and divide it by the hours he worked.

The city council plans to build a new water storage tank for the community. The tank is cylindrical with a base diameter of 25 f
Stella [2.4K]

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.
