We know that V= 4/3 pi r^3
So r^3= 140/ ((4/3) pi)= 33.422538
Hence r= 3.221166
SA = 4 pi r^2
= 4 pi 3.221166^2
= 130.39 cm^2
= 130 cm^2
I honestly didn't work it out but I would try to work out this problem in a different way than what I was taught. If you did this already and you still got the same answer as before, then it is most likely correct. I know I didn't give you an answer but I still hope it helped.
