what is the value of r?

Matilda is planning a walk around the perimeter of Wedge Park, which is shaped like a circular wedge, as shown below. The walk around the park is 2.4 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, r?(hint; radians are useful.)

I know I have two equations one for the perimeter 2.4=2r+s and one for the area 0.25=0.5r^2theta. 
I have tried multiple ways but havent been able to get the correct answer.
