Solution

The correct option is A 301.6
Given, radius of the container = 4 cm
Height of the container = 10 cm

We know that,
$S u r f a c e a r e a = 2 π r h + π r^{2} = 2 \times \frac{22}{7} \times 4 \times 10 + \frac{22}{7} \times 4 \times 4$
$= 251.42 c m s q . + 50.28 c m s q .$
$= 301.7 c m s q .$
