# A conical pit of top diameter 3.5 m is 12 m deep. What is its capacity in kiloliters ?

Given diameter, d = 3.5 mSo radius, r = 3.5/2 = 1.75Depth, h = 12 mVolume of the cone = (1/3)r^{2}h=(1/3)Ã—(22/7)Ã—1.75^{2}Ã—12= (22/7)Ã— 1.75^{2}Ã—4= 38.5 m^{3}= 38.5 kilolitres [1 kilolitre = 1m^{3}]Hence the volume of the conical pit is 38.5 kilolitres.
