Answer :

The area of a circle is given by A=Pi*r^2, and its perimeter, P=2*Pi*r.

To get the radius r, you must divide 452.2 by Pi, and then calculate the square root of this quotient.

To get the circumference or perimeter, use the radius in the formula P=2*Pi*r.

Finally, round the number you get to the nearest tenth.
