Question

Find the volume of a spherical ball of radius 14 cm.​

Answer 1

Step-by-step explanation:

Radius of the ball=14cm=r

We know that

$\boxed{\sf Volume_{(Sphere)}=\dfrac{4}{3}\pi r^3}$

$\\ \sf\hookrightarrow \dfrac{4}{3}\times \dfrac{22}{\cancel{7}}\times \cancel{(14)}^3$

$\\ \sf\hookrightarrow 88\times 196$

$\\ \sf\hookrightarrow 17248cm^3$

Thus

Volume of the spherical ball is 17248 cubic cm.

Answer 2

Answer:

→ → volume of sphere is

3

4

πr

3

So, volume of sphere =

3

4

×π×r

3

=

3

4

×π×(14)

3

=34,496

→ surface Area of sphere is =4πr

2

So, surface of sphere =4πr

2

=4×π×(14)
