Find its capacity in litres. $2425.51$ $2657.15$ $1236.5$ None of these Reveal answer Fill a bubble to check yourself A Correct answer Explanation Volume of hemisphere = (2/3) * pi * r^3 = (2/3) * (22/7) * (1.05)^3 = (2/3) * (22/7) * 1.157625 = 2.4255175 cubic meters. 1 cubic meter = 1000 liters. Capacity = 2425.5175 liters.
