Question

गोले का घनफल पता करो जिस की सतह का क्षेत्रफल 154 सेंटीमीटर है​

Answer 1

Answer:

133................

Answer 2

Given:

Surface area is 154 cm cube​

To find:

The volume of the sphere

Solution:

Formulas to be used:

$\boxed{\bold{Surface\:area\:of\:sphere = 4\pi r^2}}\\\\\boxed{\bold{Volume\:of\:sphere = \frac{4}{3} \pi r^3}}$

Using the surface area formula, we can form an equation as:

$4\pi r^2 = 154$

$\implies r^2 = 154 \times \frac{7}{22} \times \frac{1}{4}$

$\implies r^2 = 7 \times 7 \times \frac{1}{4}$

$\implies r^2 = 12.25$

$\implies r= \sqrt{12.25}$

$\implies \bold{r = 3.5 \:cm}$

Now, using the formula of volume, we get

The volume of the given sphere is,

= $\frac{4}{3}\times \frac{22}{7} \times (3.5)^3$

= $\frac{4}{3}\times \frac{22}{7} \times 42.875$

= $\bold{179.67\: cm^3 }$

Thus, the volume of the sphere is → 179.67 cm³.
