Question

5. The diameter and height of a right circular cone are 7 cm and 12 om respectively. Find the
volume of the cone in cm​

Answer 1

$\boxed{ \huge \red{\mathfrak{solution}}}$

Given:

• Diameter=7cm or radius =3.5cm

and

•Height=12cm

To find,

• volume of cone

$\boxed{ </strong><strong>\</strong><strong>b</strong><strong>l</strong><strong>u</strong><strong>e</strong><strong>{</strong><strong>\frac{1}{3 } \pi {r}^{2} h</strong><strong>}</strong><strong>}$

Put the values

$\rightarrow \frac{1}{3} ( \frac{22}{7} )(3.5)(3.5)(12) \\ \rightarrow \frac{3234}{21} \\ \rightarrow154cm ^{3}$

Hence the volume of cone is

$\boxed{ \</strong><strong>p</strong><strong>u</strong><strong>r</strong><strong>p</strong><strong>l</strong><strong>e</strong><strong> {154 {cm}^{3} }}$
