Answer 1

radius is 6 which is shown in the figure

you just need to use it in the formula

Answer 2

905

Explanation:

The volume of a sphere is

`V=(4)/(3)\pi r^3`

so the radius is 6cm (given)

`V=(4)/(3)\pi (6)^3\\\\V=(4)/(3)\pi *216\\\\V=4 *72\pi\\\\V=288\pi \\\\V=904.77868423386045267724129438449683064878478702003047644078404258...\\\\V=905cm^3`
