Find the volume of a sphere whose surface area is 154 `c m^2`

Explanation

Surface area of a sphere is `154cm^2`

Now, `4pir^2=154`

`4xx22/7xxr^2=154`

`r^2=49/4`

`r=7/2cm`

Volume of a sphere = `4/3pir^3`

Volume of a sphere = `4/3xx22/7xx(7/2)^3`=`179.67cm^3`

Hence, volume of a sphere is `179.67cm^3`.
