Question

The diameter of a sphere is 2.14 cm . Calculate the volume of a sphere to the correct number of significant figures​

Answer 1

So on putting the values we will get the radius as =2.14/2=1.07 . Since, the formulae of volume of sphere of radius r is =4/3*π*r^3 . Now, again putting the values we will get the volume as =4/3×3.14×(1.07)^3. So, the volume of sphere will be =5.128 cm^3.
