Question

The formula for the lateral surface area of a cylinder is s=2πrh, where r is the radius of the bases and h is the height.

Answer 1

D
$s = 2\pi \times r \times h \\h = \frac{s}{2\pi \times r}$

Answer 2

Lateral surface area of cylinder = 2*$\pi$ *r * h

S = 2*$\pi$ *r * h

Solve for h means we have to make h alone. As there is a multiplication sign between 2 , $\pi$ , r and h so we will use opposite operation of multiplication which is division.

So to make h alone, we will divide by side by 2*$\pi$ * r

h = $\frac{S}{2\pi \times r}$

Option D is the answer
