a) 5.2 cm
b) 5.5 cm
c) 11 cm
d) 22 cm
Answer: b
Explanation: Volume of the cylinder :
= Volume of the cube
= (11)3 cm3
= 1331 cm3
Let the radius of the base be r cm
$$\eqalign{
& \frac{{22}}{7} \times {r^2} \times 14 = 1331 \cr
& {r^2} = \frac{{1331}}{{44}} = \frac{{121}}{4} \cr
& r = \frac{{11}}{2} \cr
& r = 5.5 \cr} $$
