Lateral surface area of cylinder = 2*[tex] \pi [/tex] *r * h
S = 2*[tex] \pi [/tex] *r * h
Solve for h means we have to make h alone. As there is a multiplication sign between 2 , [tex] \pi [/tex] , 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*[tex] \pi [/tex] * r
h = [tex] \frac{S}{2\pi \times r} [/tex]
Option D is the answer
