Question

what should be multiplied with the volume of a right circular cylinder of base radius r and height h to obtain the curved surface area

Answer 1

Answer:

we know that volume is πr²h

and curve surface area is 2πrh

so let the the number be X which is to be multiplied

then As per the question

πr²h*X=2πrh

X=2πrh÷πr²h

X=2/r

Therefore, 2/r should be multiplied so that the volume becomes the curve surface area.

Thank you.
