Answer 1

Answer:

r = d÷2 = 14 cm. sphere's diameter is equal to 14 cm

Answer 2

Given:

• Diameter of circle = 28cm

To Find:

• Volume of sphere?

Solution:

Here, we have given that diameter of circle is 28 and we have to find that what is the volume of sphere?

We Know That:

• $\large{\sf{Volume~of~sphere~=~\dfrac{4}{3}πr³}}$

Where,

• π = 22/7
• r = radius of sphere = diameter/2 = 28/2 = 14cm

Let put value:

$\large{\sf{Volume~of~sphere~=~\dfrac{4}{3}πr³}}$

$\implies\large{\sf{Volume~of~sphere~=~\dfrac{4}{3}×\dfrac{22}{7}×14³}}$

$\implies\large{\sf{Volume~of~sphere~=~\dfrac{88}{21}×2744}}$

$\implies\large{\sf{Volume~of~sphere~=~\dfrac{241472}{21}}}$

$\implies\large{\sf{Volume~of~sphere~=~11498\dfrac{2}{3}}}$

Hence,

• $\large{\boxed{\bf{Volume~of~sphere~=~11498\dfrac{2}{3}cm³~or~11498.67cm³}}}$
