Question
A right circular cylinder having diameter 21 cm & height
38 cm is full of ice cream. The ice cream is to be filled in cones of height 12 cm and diameter 7 cm having a hemispherical shape on the top. The number of such cones to be filled with ice cream isSolution
Diameter of cylinder = 21 cm Height of cylinder = 38 cm The diameter of cone = 7 cm The height of cone = 12 cm The diameter of Hemisphere = 7 cm Let 'R' be the radius of Cylinder, 'r' be the radius of Cone, 'H' be the height of Cylinder and 'h' be the height of Cone R = 21/2 cm, H = 38 cm, r = 7/2 and h = 12 cm Let number of cone be n, then According to the question
