Answer 2

Answer:

Given :-

• A right circular cone of radius 6 cm and height 7 cm.

To Find :-

• What is the volume of right circular cone.

Formula Used :-

$\clubsuit$ Volume Of A Right Circular Cone Formula :

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

where,

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

Solution :-

Given :

• Radius (r) = 6 cm
• Height (h) = 7 cm

According to the question by using the formula we get,

$\longrightarrow \sf Volume_{(Cone)} =\: \dfrac{1}{3} \times \dfrac{22}{7} \times (6)^2 \times 7$

$\longrightarrow \sf Volume_{(Cone)} =\: \dfrac{1}{3} \times \dfrac{22}{7} \times 6 \times 6 \times 7$

$\longrightarrow \sf Volume_{(Cone)} =\: \dfrac{1}{3} \times \dfrac{22}{7} \times 36 \times 7$

$\longrightarrow \sf Volume_{(Cone)} =\: \dfrac{22}{\cancel{21}} \times {\cancel{252}}$

$\longrightarrow \sf Volume_{(Cone)} =\: 22 \times 12$

$\longrightarrow \sf\bold{\red{Volume_{(Cone)} =\: 264\: cm^3}}$

${\small{\bold{\underline{\therefore\: The\: volume\: of\: right\: circular\: cone\: is\: 264\: cm^3\: .}}}}$
