@RadEn  help me plz

shrutipande9 · Answer

i will give u a hint-check out the radii of both the circles

anonymous · Answer

um how to find the radii of both of a circle ??

shrutipande9 · Answer

the image shows a number line....count the no form the centre to circumference....

anonymous · Answer

r=4

shrutipande9 · Answer

correct

anonymous · Answer

um then how to prove that both circles are similar ??

shrutipande9 · Answer

see the radius of other circle....both are in proportion

anonymous · Answer

how ?

shrutipande9 · Answer

i m srry luka..:(

hartnn · Answer

All circles are similar to each other! Always. 
no matter what their radius is...

anonymous · Answer

i know that the circles are similar but i need to prove that both circles are similar

hartnn · Answer

does this question belong to topic dilation or translation or something ?

anonymous · Answer

non

anonymous · Answer

the question only says to Prove that the two circles shown below are similar.

hartnn · Answer

maybe the theorem shown here will help, http://www.jamestanton.com/wp-content/uploads/2012/03/Curriculum-Newsletter_January-2013.pdf Theorem: Any two circles are similar. Proof: Given a circle of radius r and a second circle of radius R , perform a translation so that their centers coincide. A dilation from the common center of the circles with scale factor R takes the points of one circle and maps them onto the second. Thus we have mapped one circle onto the other via a translation and a dilation. The circles are similar.
