A conical tank in a Chennai factory holds exactly 11 kilolitres of liquid. Its base radius is 3.5 m. Find its height in metres. (Use π = 22/7, 1 kilolitre = 1 m^3)

Question

Accepted Answer

0.857. 11 = 1/3(22/7)(3.5^2) h. Base factor = 1/3(22/7)(49/4) = 22 × 49/3 × 7 × 4 = 154/12 = 12.8333. So h = 11/12.8333 = 132/154 = 6/7 = 0.857 m (approx).
