The heights of two cylinders are equal. The radii are R and r. Then the ratio of their volumes isA) R2 : r2B) R : r3C) R : r2D) R2 : r |
|
Answer» Correct option is: A) R2 : r2 \(\frac {V_1}{V_2} \) = \(\frac {\pi \, r_1^2h_1}{\pi \, r_2^2 h_2} = \frac {\pi R^2h}{\pi r^2h} = \frac {R^2}{r^2} = R^2 : r^2\) Hence, the ratio of their volumes is \(R^2 : r^2\). Correct option is: A) R2 : r2 |
