A cylindrical bucket, 32 cm high and with radius of base 18 cm, is filled with sand. This bucket is emptied out on the ground and a conical heap of sand is formed. If the height of the conical heap is 24 cm, find the radius and slant height of the heap.

Height of the cylindrical bucket =32 cm

Radius of the cylindrical bucket = 18 cm


Volume of the bucket = πr2 h


× 182 × 32 cm3



Height of the conical heap =24 cm


Let Radius of the conical heap =r cm


Volume of conical heap



Volume of conical heap=Volume of cylindrical bucket




r2 = 1296 cm



r = 36 cm
