Answer:
Step-by-step explanation:
Cylinder:
d= 6cm; r =6/2 = 3cm
h =7.5cm
Volume of ice cream in cylinder = πr²h
= π * 3 * 3 * 7.5 = 67.5 π cubic cm
Cone:
h = 6 cm;
d = 3cm ; r = 3/2 = 1.5cm
Volume =(1/3)πr²h
= (1/3) * π * 1.5 * 1.5 * 6
= π * 1.5*1.5 * 2 = 4.5π cu. cm
Hemisphere on top:
r = 1.5cm
Volume = (2/3)πr³
=(2/3)* π * 1.5 *1.5 * 1.5
= 2 *π * 0.5*1.5*1.5
= 2.25π cu.cm
Volume of ice cream in each cone = 4.5 π + 2.25π = 6.75π cubic cm
No of cones = volume of cylinder/ Volume of ice cream in each cone
=π *67.5 / 6.75 * π
= 67.5 * 100 / 6.75 * 100
= 6750 / 675
= 10
number of cones which can be filled with ice cream = 10 cones
