Question

If the height and diameter of a cylinder are doubled, the new volume of
the cylinder will be.​

Answer 1

Answer:

8*(Vol of original cylinder)

Step-by-step explanation:

we know that, volume of cylinder = π$r^{2}$h

given that height and diameter are doubled.

So, replacing r by 2r and  by 2h in the above formula,

vol of new cylinder = π(2r)^2*(2h)

                                = π*r^2*h*4*2

                                = 8*(π*r^2*h)

                                = 8*(vol of original cylinder)

So, the volume of the new cylinder is 8 times the vol of the  original cylinder.
