SSC GD 2024 PYQ — Question 57

The correct answer is option 1 i.e. 2772 cm³.

The volume of a cone (V) = $\frac{1}{3} \pi r^2 h$

(r) is the radius of the base = 10.5 cm.
(h) is the height of the cone = 24 cm.

$\pi \approx 3.1416$
⇒ V = $\frac{1}{3} \pi (10.5)^2 (24)$

⇒ V = $\frac{1}{3} \times 3.1416 \times 110.25 \times 24$

⇒ V  = $\frac{1}{3} \times 3.1416 \times 2646$

⇒ V = $\frac{1}{3} \times 8316.05$

⇒ V = 2772.02 cm³  or 2772 cm³
