Answer:

solution,

    circumfrence of a circle (p) = 42.7m

         

from formula of circumfrence of a circle,

               p = 2πr

          or, 42.7 = 2 × 3.14 ×r

or, 42.7/6.28 = r

∴ r = 6.80m

area of the circle (A) = 2πr²

                                 = 2× 3.14 × 6.80² = 290.36m²

as we know,

   diameter of the circle(d) = 2r = 2×6.80 = 13.60m
