@Raghav Vaidyanathan , i got my answer as $$4+4\frac{\sqrt{6}}{3}$$ · 2 years ago

A tetrahedron is formed of side $$4~cm$$. The height of tetrahedron from its base to the centre of sphere is $$4\frac{\sqrt{6}}{3}$$, and $$2~cm$$ below the base lies the plane, and $$2~cm$$ above the centre is the top, did i do correctly · 2 years ago

Looks like it's correct to me. I checked it right now. · 2 years ago

The ans is 2$$\sqrt{\frac{8}{3}}$$ · 2 years ago
