Chapter:19 (Mensuration of Sphere)

Question 1:

The surface area of a sphere of radius ‘r’ is

\(4 π {r^3}\) \(4 π {r^2}\) \(π {r^2}\) \({\frac{4}{3}}π{r^3}\)

Question 2:

The volume of a sphere of diameter D is

\({\frac{4}{3π}}{D^3}\) \(4 π {D^2}\) \({\frac{π}{6}}{D^3}\) \({\frac{π}{4}}{D^2}\)

Question 3:

If R and r are the external and internal radii of spherical shell respectively, then its volume is

\({\frac{4}{3}}π{({R^3}-{r^3})}\) \({\frac{4}{3}}π{({R^3}-{r^3})}\) \(4π({R^3}-{r^3})\) \({\frac{4}{3}}{({R^3}-{r^3})}\)
