For a sphere of radius 10 cm, the numerical value of the surface area in how many percent of the numerical value of its volume:
OPtion
1) 26.5 %
2) 25 %
3) 24 %
4) 27 %
5) 30 %
6) 34.5 %
7) 45 %
8) 46.5 %
9) 48 %
10)None of these

• Surface Area= 4*pi*r*r=400*pi
  Volume= (4*pi*r*r*r)/3=4000*pi/3
  Percentage= [(400*pi)/(4000*pi/3)]*100
  = 30%
  
  So option (5)

• ans =30% option 5;
  (4/3 pie r^3*x)/100=4 pie r^2;
  x=30%
