A cylindrical water tank has a radius of 6 feet and a height of 20 feet. A larger tank with the same height has a volume that is
likoan [24]

Answer:

Radius of large cylinder = 10.39 feet\\

Step-by-step explanation:

Volume of the larger tank is three times the volume of smaller tank

Volume of smaller tank

= \pi r^{2} h\\= (3.14) * 6^{2} * 20\\= 2260.8 ft^{3} \\

Volume of larger tank

= 3 * 2260.8 ft^3\\= 6782.4 ft^3\\

Or it can also be written as

\pi r^{2} h = 6782.4 ft^3\\(3.14) * ( r^2) 20 = 6782.4 ft^3\\r^2 = 108\\r = 10.39

a parking garage charges $2.50 base free plus an hourly rate of $4.00. If you hve most $12.50 how many parking you can​
snow_lady [41]

Answer: 2.5 hours or 2 hr and 30 min

Step-by-step explanation:

We can set up an equation to find how many hours you can park.

2.5+4x=12.5

The 2.5 comes from the base fee. The 4x is the hourly rate, where x is hours. The 12.5 is the total amount of money you have.

Since we have our equation, we can solve for x.

4x=10

x=2.5

You can park for 2.5 hours, or 2 hours and 30 min.
