Hint:

Familiarize yourself with standard volume and surface area formulas of 3D shapes: cone, cylinder, sphere.

Answer 1

The Correct Option is C

- (A) Volume of cone = $\frac{1}{3} \pi r^{2} h$ (Formula for cone's volume)
- (B) Curved surface area of cylinder = $2 \pi r h$ (Lateral surface area without bases)
- (C) Total surface area of cone = $\pi r (l + r)$ (Sum of base area and curved surface)
- (D) Volume of sphere = $\frac{4}{3} \pi r^{3}$ (Complete volume formula)
