Question

find the capacity in litres of a conical vessel with radius 7cm,slant height 25cm​

Answer 1

Step-by-step explanation:

We know that volume of cone is 1/3 pi r^2 h

r^2+h^2=l^2

Solve it.......

Answer 2

Answer:

Radius of cone = 7 cm

Slant height (l) of cone = 25 cm

$\\ \tt \: Height \: \: of \: \: cone \: \: (h) = \sqrt{ {l}^{2} \: - {r}^{2} } \\ \\ \\ \implies \tt \: \sqrt{ {25}^{2} - {7}^{2} } \\ \\ \\ \implies \tt \: 24 \: \: cm$

_____________________________

$\sf{Volume\:\:of\:\:cone}$ = $\tt\dfrac{1}{3}\:\pi\:r^2\:h$

$\implies$ $\tt{154×8}$

$\implies$ $\tt{1232}$ cm³

$\tt\bigg(\dfrac{1232}{1000}\bigg)$ = 1.232 litres.
