Answer:
48.7 cube inches
Step-by-step explanation:
Let us assume that the ice cream filled the entire volume of the cone.
Diameter of cone = 4 inches
height of cone = 7 inches
diameter of a sphere of ice cream = 5 inches
Total amount of ice cream = volume of cone + volume of sphere
volume of cone = 

h
r = 
=
= 2 inches
volume of the cone =
x
x
x 7
=
x
x 4 x 7
= 29.3333 cube inches
volume of sphere =


r = 
=
= 2.5 inches
volume of sphere ice cream =
x
x 
=
x
x 
= 19.40 cube inches
So that,
Total amount of ice cream = 29.33 + 19.40
= 48.7 cube inches
