Its volume is: pi*0.202*2.5 = 1/10 times pi cubic meters

330.78 ft3
One square meter of area.
Volume of a cylinder = pi*r2*h So, I assume you mean 8' in diameter, which is 4' in radius. Volume = pi(4')2(6') = 302 cubic feet in volume ----------------------------------
A circular tank is 12 meter in diameter and 7.5 meter in height. how much water does it hold when half full?
Twice as much as the radius
Its volume is: pi*0.202*2.5 = 1/10 times pi cubic meters
need more info, so sorry. What is the question? the diameter is the widest part all the way across a circle. They are not similar to kilometer and meter and centimeter other than in that kilometer, meter, and centimeter can be diameters.
That depends on the diameter of the pipe.

A cubic metre, a tonne, 1000 litres
(0.45/2)2 x pi x 2 = 1/3rd of a cubic meter
It depends on the diameter of the straw, which varies. Multiply the diameter by 3.14 and the result by the length of the straw.
I think it would be 697 gallons.
10*10*0.8 = 80 m3
Usually you can use the formula for a cylinder, as a good approximation for the shape of the jar.
