A cylinder circumscribes a sphere. The ratio of their volume is :
Answer & explanation
Correct answer: option 1
A cylinder circumscribes a sphere
Height of cylinder = 2 × radius of sphere
= 2r
Volume of cylinder : volume of sphere
πr²h : \(\frac{4}{3}\)πr³
r²×2r : \(\frac{4}{3}\)r³
3 : 2
The correct answer is option (1) : 3 : 2
