SSC GD Constable (English) - 22nd November 2021 Shift 3 • Quantitative Aptitude • Q74

The curved surface area of a right circular cylinder of height 14 cm is 176 cm2. What is the area (in cm2) of the base of the cylinder? (Take π=227\pi=\frac{22}{7})

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e.  887\frac{88}{7}

The curved surface area of the cylinder = 2π\pirh

176 = 2 × 22/7 × r × 14

r = 2 cm

Area of the base = π\pir2 = 22/7 × 4 = 88/7 cm2
