Step-by-step explanation:
let the radius of 1 sphere be r and 2 sphere be R
ATQ
r+R=5
volume of sphere= 4/3πr^3
ratio of their volume= 4/3πr^3/4/3πR^3=27/8
=r^3/R^3= 27/8
= r/R=3/2
Surface area of sphere = 4πr^2
surface area of 1 sphere = 4×22/7×3×3=792/7
surface area of 2 sphere= 4×22/7×2×2 = 352
difference in surface area=792/7-352/7
= 62.86
I hope it is helpful to you
Plz mark be brainliest ❤️
