@tyfutiuio dimension of a circle means radius of a circle
it is give dimension of circle B = 3 * dimension of circle A 
that is rB = 3* rA where rA and rB are radius of circle A and B respectively
area of circle B is given
formula for area of circle = pi * sqr(r)
use the value of area of circle B and solve for rB?
