A right circular cylinder has a height of ​ 20 1/2 ​ ft and a diameter ​ 1 1/5 ​ times its height.
BARSIC [14]

Answer:

It would be 9,738.54

Step-by-step explanation: For starters, V= r^2(3.14)h

Make things easier by changing 20 1/2 to 20.5)) and 1 1/2 to 1.2))

Now multiply them to get your diameter. 20.5 * 1.20= 24.6.  

You now have a diameter of 24.6. Now, divide 24.6 by 2 to get your radius. So, now you have a radius of 12.3. All you have to do now is plug in your numbers.

V= r^2(3.14)h       V= (12.3)^2 (3.14) 20.5

you should get 9738.5373, but rounding by the hundredths place gets you 9738.54

Do well on your tests guys!
