We are given that there
will be (1/2) a litre after the first pouring, so considering two successive
pourings (n and (n+1)) with 1/2 litre in each before the nth pouring occurs:
1/2 × (1/n) = 1/(2n)
1/2 - 1/(2n) = (n-1)/2n
1/2 + 1/(2n) = (n+1)/2n
(n-1)/2n and (n+1)/2n in
each urn after the nth pouring
Then now consider the
(n+1)th pouring
(n+1)/2n × 1/(n+1) =
1/(2n)
(n+1)/(2n) - 1/(2n) =
n/(2n) = 1/2
Therefore this means that after
an odd number of pouring, there will be 1/2 a litre in each urn
Since 1997 is an odd
number, then there will be 1/2 a litre of water in each urn.

Answer:
r=5
Step-by-step explanation:
Circumference of a circle =
Since w are given that the circumference of circle is 31.4 cm
So,
[tex5= r[/tex]
So, radius of given circle is 5 cm
Area of circle =
=
=
Thus the area of circle is 78.5 sq.cm.
Hence the radius of given circle is 5 cm and the area of the circle is 78.5 sq.cm.
