i will definitely mark him a brainlist who solves this correctly. This is urgent please give me answer fast . the que is............................................................... find the ratio between area and circumference if radius is halved..... give the solution fast with steps....

Answer»

Hey.

LET radius be r.

new area of a circle = PI*(r/2)²

= pi*r²/4

new CIRCUMFERENCE of a circle = 2*pi*r/2

= pi*r

so RATIO = pi*r²/4 / pi*r

= r/4

hope it helps you!!
