Answer:
1078
Step-by-step explanation:
In the question,
Radius of hemisphere
= Radius of cone
= height of cone
= 7 cm
(∴∴height of hemisphere = radius of hemisphere)
Volume of ice cream
= Volume of hemisphere part + volume of conical part
=23×227×(7)3+13×227×72=23×227×(7)3+13×227×72
=227×73=22×72=227×73=22×72
=1078cm3
