Question

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

Answer 1

GIVEN:-

Radius => 7cm

Slant height => 25cm

VOLUME of cone => 1/3 πr²h

we know that ,

Slant height => √(h²+r²)

25 = √(h²+49)

625 = h²+49

h²= 625-49

h²=576

h=√576

h=24 cm

Now,

volume => 1/3 *22/7*49*24

=>1232 cm³

Converting into litre :-

1000cm³=>1L

•°• 1.232L is the right answer ✔️

Answer 2

Answer:

hope it helps you

Step-by-step explanation:

radius= 7cm

slant height= 25cm

we, know that

l²=r²+h²

(25cm)² = (7cm)² + h²

625cm² = 49cm² + h²

625cm² - 49cm² = h²

576cm² = h²

h = √576cm²

h = 24cm

Volume of cone = 1/3πr²h

1/3×22/7×7cm×7cm×24cm

1232cm³

this is your answer 1232÷1000l

=1.232l
