SSC GD Const 2025 (English) - 05 Feb 2025 - Shift 3 • Quantitative Aptitude • Q49

If the radius of a hemisphere is 13√3 cm, find its curved surface area.

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 1014π cm2.

Radius = 13√3 cm

Curved Surface Area (CSA) of a hemisphere = 2πr²

r² = (13√3)² = 169 × 3 = 507

Now: CSA = 2π × 507 = 1014π cm²
