The volume of a right circular cylinder of base radius r is obtained by multiplying its curved surface area by:

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. r2\frac{r}{2}.

Volume of cylinder(V) = πr2h

Curved Surface Area (CSA) = 2πrh

So,

⇒ VCSAV\over CSA = πr2h2πrhπr^2h\over2πrh = r2\frac{r}{2}

Volume = CSA × r2\frac{r}{2}
