Question

12. The circumference of the
base of cylindrical vessel is 88
cm and its height is 25cm.
How many litres of water can it
hold? (1000 cm3= 1L) (Assume
n = 22/7)​

Answer 1

Answer:

15.4 litres

Step-by-step explanation:

let the radius be r

we know that, perimeter= 2πr = 88 cm

so,

r=14 cm

volume of cylinder = πr^2 h

volume = π*14*14*25

= 15,400 cm^3

1000cm^3= 1 L

so,

volume = 15,400/1000

=15.4 litres

Answer 2

Answer:

Number of litres of water=volume of cyclinder πr2h

Here height=25cm

let radius=r

now circumference of base =88cm

2πr=88

r=14cm

Number of litres of water =πr2h

22/7×14×14×25 cm3=15400cm3

15400×(1/1000)=15.4 litres

vessel can hold water=15.4 litres
