Question #ee994

Answer 1

No. of cones that can be made `~~ color(brown)(126`

Explanation:

Volume of solid sphere `= (4/3)pi r^3`
`r = 10.5 cm`

`:. Vol of sphere = (4*22*10.5^3)/(3*7)`
`= 4849 cm^3`

Volume of cone `= (1/3)pir^2h`
`r = 3.5 cm, h = 3 cm`

`:.`Volume of one cone =`(22*3.5^2*3)/(3*7)`
`= 38.5 cm^3`

No. of cones that can be made from solid sphere
= (vol. of sphere )/(vol. of cone)

`= 4849 / 38.5 ~~ color(brown)(126`
