Matilda is planning a walk around the perimeter of Wedge Park, which is shaped like a circular wedge. The walk around the park is 2.1 miles, and the park has an area of 0.25 square miles. If θ is less than 90 degrees, what is the value of the radius.

  • Math... - ,

    area wedge= 2PI r^2*theta/360 where theta is in degrees

    perimeter= 2r+ theta/360 * 2PI r

    Can you take it from here?
