Correct Answer: Option C

Explanation

Volume of a cone = \(\frac{1}{3} \pi r^2h\)

h² = 5² = 3²

= 25 - 9 = 16

h = \(\sqrt{16}\)

h = 4cm

v = \(\frac{1}{3} \times \frac{22}{7} \times 3^2 \times 4\)

\(\frac{1}{3} \times \frac{22}{7} \times 9 \times 4\)

= \(\frac{22 \times 3 \times 4}{7}\)

= 37.7cm³

= 38cm³
