A cylinder has radius of 7cm and its volume is 1540cm^3, what is the height of the cylinder? (Take π = \(\frac{22}{7}\))
A. 10cm
B. 14cm
C. 11cm
D. 15cm
This question was posed to me in an online interview.
The origin of the question is Volume of a Cylinder in section Surface Areas and Volumes of Mathematics – Class 9
Correct answer is A. 10cm
The best I can explain: Volume of a cylinder having radius r and height h is equal to πr^2h.
πr^2h = 1540
\(\frac{22}{7}\) * 7 * 7 * h = 1540
h = 10cm.
