Given Ratio of volume of two spheres = 125 : 64 Formula used surface area of sphere =4πr2 Volume of sphere = (4/3)πr3 Where r is radius respectively Calculation [(4/3)πR3/(4/3)πr3] = 125/64 Where R and r are radius of two sphere ⇒ R3/r3= 125/64 ⇒ R = 5r/4 surface area of 1st sphere/Surface area of 2nd sphere =[4π(5r/4)2]/4πr2 ⇒ 25 : 16 ∴ Ratio of surface area of two spheres is 25 : 16.
