Question

For a sphere of radius 10 cm, the numerical value of the surface area is how many percent of the numerical value of its volume :​

Answer 1

Volume constitutes the inner portion of a figure which can be filled with some content

But surface area is the outer portion the covering of the figure

Hence covering has no relation with inner content

Like in a balloon the membrane has no relation with the amount of air inside it

It just provides shape to a figure

Answer 2

surface area of sphere =.

$4\pi {r}^{2}$volume of sphere =

$\frac{4}{3} \pi {r}^{3}$

now we see that surface area =1256 cm^2

volume is equal to 4186.6 cm^3

now divide surface by volume ×100

1256/4186.6 ×100= 30%

it is 30 percent of the numerical value of volume of sphere
