There is a formula in chemistry regarding the Bohr's radius of hydrogen atom

r = r°n×n÷z

In this formula R is the radius and n is the radius in which the electron is lying

Z is the atomic number of the atom in the case of hydrogen atom Z is equal to one

r°=0.529

Therefore for Bohr's radius of third Orbit n is equal to 3

r= 0.529 × 3×3

r=4.761

Remember this value comes in A°

Therefore radius of third orbit is 4.761
