Question

The capacity in litres of a conical vessel with radius 7 cm and height 21 cm is​

Answer 1

Step-by-step explanation:

given

radius of conical vessel=7cm

height of conical vessel=21cm

so,

volume of conical vessel

$\frac{1}{3} \pi {r}^{2} h \\ = \frac{1}{3} \times \frac{22}{7} \times {7}^{2} \times 21 \\ = 22 \times 7 \times 7 \\ = 1078 {cm}^{3}$

we know that,

1cm^3=1/1000litres

hence:-

the capacity of conical vessel

=1078*1/1000

=1.078litres
