Answer 2

Answer:

Given :-

• A cone whose radius is 4 cm and height is 14 cm.

To Find :-

• What is the volume of cone.

Solution :-

Given :

$\mapsto \bf Radius_{(Cone)} =\: 4\: cm$

$\mapsto \bf Height_{(Cone)} =\: 14\: cm$

According to the question by using the formula we get,

$\implies \sf\boxed{\bold{Volume_{(Cone)} =\: \dfrac{1}{3}{\pi}r^2h}}$

where,

• π = Pie or 22/7
• r = Radius
• h = Height

So, by putting those values we get,

$\implies \sf Volume_{(Cone)} =\: \dfrac{1}{3} \times \dfrac{22}{7} \times (4)^2 \times 14$

$\implies \sf Volume_{(Cone)} =\: \dfrac{1 \times 22}{3 \times 7} \times (4 \times 4) \times 14$

$\implies \sf Volume_{(Cone)} =\: \dfrac{22}{21} \times 16 \times 14$

$\implies \sf Volume_{(Cone)} =\: \dfrac{22}{21} \times 224$

$\implies \sf Volume_{(Cone)} =\: \dfrac{22 \times 224}{21}$

$\implies \sf Volume_{(Cone)} =\: \dfrac{4928}{21}$

$\implies \sf Volume_{(Cone)} =\: 234.67$

$\implies \sf\bold{\underline{Volume_{(Cone)} =\: 234.67\: cm^3}}$

$\therefore$ The volume of cone is 234.67 cm³ .
