volume of sphere is 4/3πr³
606.375=4/3 x 22/7 x r³
606.375= 88/21r³
606.375/88 x 21=r³
14553/88=r³
165.375=r³
r =5.24
total surface area is 4πr²
=4 x 22/7 x 5.24 x 5.24
= 88/7 x27.45
=2415.6/7
=345.18m²...

ANS ]
volume of sphere =4/3 π r^3
Given volume = 606.375
therefor. 4/3πr^ 3=606.375
r^3= 606.375/πx(3/4)
= 144approx
r =5.24
surface area of sphere =4πr^2
= 4x3.14x(5•24)^2
=358.155936
