A cylindrical glass has internal radius $3.5$ cm and height $10$ cm. How many litres of juice can it hold? (Use $\pi=\dfrac{22}{7}$.)
  1. $0.385$ L
  2. $0.770$ L
  3. $3.85$ L
  4. $0.155$ L

Solution

$V = \dfrac{22}{7} \times 3.5^{2} \times 10 = \dfrac{22}{7} \times 12.25 \times 10 = 385 \text{ cm}^{3} = 0.385$ L.
