HEY BUDDY YOUR ANSWER IS GIVEN BY UDIT
GIVEN r1/r2=3/2
Circumference of circle is 2πr
where r is radius
ratio of circumference of C1 and C2
(C1=circle 1 and C2=circle 2 )
now ratio = 2πr1/2πr2
=r1/r2
so the ratio of circumference is same as ratio of radii
so the answer is 3/2

i m sorry but ratio wasn't asked in this question
circumference was asked..
so you are wrong..
ok
is the question right

the radii of first circle=3r
the radii of second circle=2r
circumference of circle=2πr
therefore, circumference of first circle=2π3r=6πr
circumference of second circle=2π2r=4πr
the radii of second circle=2r
circumference of circle=2πr
therefore, circumference of first circle=2π3r=6πr
circumference of second circle=2π2r=4πr
panku do u know the answer
why not..
ask ur teacher
in many questions we are told to take..even if it is not given
but answer come in independent form
not always
sometimes in surface are and volume..it may come in variable form
but that variable form
u will come to know this later
stop this now
