Answer:

3 cm

Step-by-step explanation:

  • V_{cylinder} = 189\pi \: cm^3 (Given)

  • h_{cylinder} = 21\: cm (Given)

  • Formula for V_{cylinder} is given as:

  • V_{cylinder} = \pi r^2h

  • \implies  189\pi = \pi r^2(21)

  • \implies \frac{ 189\pi}{21\pi} = r^2

  • \implies 9 = r^2

  • \implies \pm\sqrt 9 = r

  • \implies \pm 3 = r

  • Length of radius can not negative

  • \implies r = 3 \: cm

Hope it helps you in your learning process.
