Expert Answer:

Volume or amount of ice cream in cylindrical container = πR2H = (3.14)(6)(6)(15)

Let h - height of conical portion, r - radius of conical portion.

h = 4r.

Amount of ice cream in one ice cream cone = Volume of hemispherical top + Volume of cone

= (4πr3/3)/2 + πr2h/3

= 2πr3/3 + 4πr3/3

= 2πr3

Amount of ice cream in 10 such cones = Total amount of ice cream,

10(2πr3) = (3.14)(6)(6)(15)

r3 = (6)(6)(15)/20

r = 3 cm
