The radius of a right circular cylinder is thrice of its height. If the height of the cylinder is 3.5 cm, then what is the volume of the cylinder?
Answer & explanation
Correct answer: option 4
Given, height of the right circular cylinder = 3.5 cm
Radius = 3 x height = 3 x 3.5 = 10.5 cm
Volume = $\pi r^2h$ = $\pi 10.5^2 3.5$
= 1212.75 cm³
