✯✯ QUESTION ✯✯

What is the volume of cone of radius of base 3cm and height 12cm ?

━━━━━━━━━━━━━━━━━━━━

✰✰ ANSWER ✰✰

$\longmapsto\tt{Radius\:of\:Cone=3\:cm}$

$\longmapsto\tt{Height\:of\:Cone=12\:cm}$

➥Using Formula : -

$\longmapsto\tt{\small{\boxed{\bold{\bold{\red{\sf{Volume\:of\:Cone=\pi{{r}^{2}\dfrac{h}{3}}}}}}}}}$

➥Putting Values : -

$\longmapsto\tt{\dfrac{22}{7}\times{3}\times{\cancel{3}}\times\dfrac{12}{\cancel{3}}}$

$\longmapsto\tt{\cancel\dfrac{792}{7}}$

$\longmapsto\tt{113.1{cm}^{3}}$

☛So , The volume of cone is 113.1 cm³...

_______________________

• C.S.A of Cone = πrl
• T.S.A of Cone = πr(l+r)
• Volume of Cone = πr²h/3
