Question

An ice cream cone has a hemispherical top. If the height of the cone is 9 cm and the base radius is 2.1 cm, find the volume of the ice cream in the ice cream cone (Round off)

Answer 1

we get that the volume of the cone is

`V=(\pi\cdot r^2\cdot h)/(3)=13.23\pi`

the volume of the hemispherical top is

`V=(4)/(6)\pi\cdot r^3=6.174\pi^{}`

so the total volume is:

`V=13.23\pi+6.174\pi=19.404\pi\approx60.95`
