Solution

The correct option is A
True

Curved surface area of the cylindrical pillar
$= 2 π r h$
$= 2 \times \frac{22}{7} \times 3.5 \times 10$
$= 220 m^{2}$

So,
$t o t a l c o s t o f p a i n t i n g$
$= C u r v e d S u r f a c e A r e a o f p i l l a r \times C o s t p e r m^{2}$
$= 220 \times 10$
= ₹ 2200/-

Hence, the given statement is true.
