Question

if the numberical value of volume and lateral surface area of a right circular cylinder are equal, then find the radius of the cylinder.​

Answer 1

Step-by-step explanation:

volume of cylinder = π r^2h

lateral surface area =2πrh

now πr^2h= 2πrh (given)

or, r^2=2r

or, r^2 -2r=0

or, r(r-2) =0

so r=0 or r=2
