To find the volume of the first cylindric ice cream. Its height is 8 centimeters and its diameter is 4 centimeters. Let's use the formula for the volume of a cylinder.

Replacing the given information, we have.
![V_{\text{cylinder}}=3.14(2)^2\cdot8=3.14\cdot4\cdot8=100.5\operatorname{cm}]()
On the other hand, we use the circular cone formula to find the volume of the second ice cream.

Let's replace the given information.
![V_{\text{cone}}=(1)/(3)\cdot3.14\cdot(2)^2\cdot11.5=48.11\operatorname{cm}]()
Then, we subtract the volumes.
![\Delta V=100.5-48.1\approx52.4\operatorname{cm}^3]()
Hence, the answer is C.
