Answer 4

@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?

Answer 5

@tyfutiuio can u write what will u get the value of rB?

Answer 6

so if you divide 225 by 3 how many will get ?
