Given:
Radius of cone is 2.6 cm and height is 6.8 cm.
The volume of cone is given as,
[tex]\begin{gathered} V_C=\pi\times r^2\times\frac{h}{3} \\ V_C=\pi\times(2.6)^2\times\frac{6.8}{3} \\ V_C=\frac{45.968\pi}{3} \end{gathered}[/tex]
Also, the radius of sphere is 2.,6 cm
[tex]\begin{gathered} V_S=\frac{4}{3}\times\pi\times r^3 \\ V_S=\frac{4}{3}\times\pi\times(2.6)^3 \\ V_S=\frac{70.304\pi}{3} \end{gathered}[/tex]
The total volume is,
[tex]\begin{gathered} V=V_C+V_S \\ V=\frac{45.968\pi}{3}+\frac{70.304\pi}{3} \\ V=\frac{116.272\pi}{3} \\ V=121.760\text{ cubic cm} \end{gathered}[/tex]
Answer: There are 121.760 cubic cm of ice cream.
