Question

Total surface area of a cylinder of radius 3h and height 6r is _________

(A) 36π×r (2r + h) (B)18π×h (2r + h) (C) 12π×r (2r + h) (D) 2π×r (r + h)​

Answer 1

Answer:

Given:-

Radius - 3h

Height - 6r

Formula:-

TSA of cylinder :-

$2\pi \: r(r + h)$

Now substitute the value of r and h

$2\pi \times 3h(3h + 6r)$

$12\pi {h}^{2} + 12\pi \: r$

Step-by-step explanation:

Hope this helps you.
