Volume of the ice cream is 72.02 cm³ (approx value).
Given data :
Radius of the hemisphere and cone = 2.5 cm
Height of the cone = 9 cm
So,
The volume of the hemisphere = 2/3 π (2.5)² = {(2/3)×(22/7)×2.5× 2.5} = 13.09 cm³
The volume of the cone = 1/3 π (2.5)²× 9 = {(1/3)×(22/7)×2.5×2.5×9} = 58.93 cm³
Total volume of the icecream = (58.93+13.09)cm³ = 72.02 cm³ (answer)
