1.	If the diameter of a sphere is 14 then find the volume of this sphere
Answer» GIVEN :- The diammeter of a SPHERE = 14 cm Solution :- $\purple{\boxed{ \bf{\sf \: Surface \: Area \: of \: Sphere = 2\pi {r}^{2} }}}$ ${ \bf{\sf \: 4 × \frac{22}{7} × 7 × 7}}$ ${ \bf{\sf \: 4 × 22 × 7}}$ $\red{\boxed{ \bf{\sf \: 616 \: {cm}^{2} }}}$ ${ \bf{\sf \: Volume \: Of \: Sphere = \frac{4}{3} \pi {r}^{3} }}$ ${ \bf{ \sf \: \frac{4}{3} × \frac{22}{7} ×7×7×7}}$ $\green{\boxed{ \bf{\sf \: 1437 \: {cm}^{3} }}}$
