Question 76
For a sphere of radius 10 cm, the numerical value of the surface area is how many per cent of the numerical value of its volume ?
Solution
Now, surface area of sphere = 4*3.142*r^2 = 4*3.142*10^2 = 1256.8
Now, volume of the sphere = 3.142*r^3 =3142
The percent of the numerical value of the surface area of the numerical value of its volume = (1256.8/3142)*100 = 40
Therefore, the correct option is option C
