# A piller 14 cm in diameter is 5 m high. How much material was used to construct it?

 A) $$\Large (77 \times 10^{2}) cm^{3}$$ B) $$\Large (77 \times 10^{4}) cm^{3}$$ C) $$\Large (77 \times 10^{5}) cm^{3}$$ D) $$\Large (77 \times 10^{3}) cm^{3}$$

 D) $$\Large (77 \times 10^{3}) cm^{3}$$

Volume of the cylinder = $$\Large \pi r^{2}h$$

= $$\Large \frac{22}{7} \times 7 \times 7 \times 500 = 77000$$

=$$\Large \left(77 \times 10^{3}\right) cm^{3}$$
