A cylinder has a diameter of 80 cm and a length of 45 cm. Another cylinder has the same volume but is 80cm long. What is the diameter of the longer cylinder?
Volume of cylinder
Volume of the other cylinder = 72000π
Solve for diameter in
72000π = π (diameter/2)²*80
I get diameter=60.
Multipy both sides of this equation with(4/pi)
Divide both sides with 125
