Question

The volume of this cone is 1,610.82 cubic meters. What is the radius of the cone?

Answer 1

`\\ \sf\longmapsto V=1610.82`

`\\ \sf\longmapsto (1)/(3)\pi r^2h=1610.82`

`\\ \sf\longmapsto \pi r^2(19)=1610.82(3)=4832.36`

`\\ \sf\longmapsto 3.14r^2=254.34`

`\\ \sf\longmapsto r^2=81`

`\\ \sf\longmapsto r=9m`
