Circumference = 2*pi*r which can be rewritten as r= C/(2*pi)
Area = pi*(r^2)
substitute with 50% of C
pi * ((1/2)(1/(2*pi))^2
What is your coefficient ?
Hi all,
i am not able to get the relation between area and circumference in the given below.could any one please help me out
If the circumference of a circle is decreased by 50% then the percentage of decrease in its area is?
