A water tank is in the shape of a right triangular cylinder with a height of 20 feet and a volume of 320 (3.14) cubic feet. what is the diameter, in feet, of the water tank?

We know the formula for the volume and the only variable we do not know is the radius (2r=diameter) Therefore by isolating r and multiplying it by 2, we will find tge diameter V = (h (pi) r^2) / 3 320 (pi) = (20 (pi) r^2) / 3 3*320 (pi) = 20 (pi) r^2 960/20=r^2 48=r^2 Sqrt (48) = r Diameter = 2 (sqrt48)
