A container shaped like a right circular cylinder having diameter 12 cm and height 15 cm is full of ice cream. The ice cream is to be filled into cones of height 12 cm and diameter 6 cm, having a hemispherical shape on the top. Find the number of such cones which can be filled with ice cream

volume of cylinder = ( volume of cone + volume of hemisphere ) * number of cones

22/7 * 6 * 6 * 15 = 22/7 ( 1/3 * 3 * 3 * 12 + 2/3 * 3 * 3 * 3 ) * n

=> 36 * 15 = ( 36 + 18 ) * n

=> 540 = 54 * n

=> n = 540 / 54

=> n = 10

**NUMBER OF SUCH CONES IS 10**
