A cylindrical container has diameter $14$ cm and height $10$ cm. Its volume is (use $\pi=\dfrac{22}{7}$):
  1. $1540 \text{ cm}^{3}$
  2. $770 \text{ cm}^{3}$
  3. $3080 \text{ cm}^{3}$
  4. $616 \text{ cm}^{3}$

Solution

$r = 7, h = 10$. $V = \pi r^{2} h = \dfrac{22}{7} \times 49 \times 10 = 1540 \text{ cm}^{3}$.
