im not sure how i can draw the specific image i have for the problem to be solved, but i'll try to explain it and then maybe someone can help me out with this. so there is a circle with radius r and center O. The points A, B, and C are on the circle and AOC = the angle θ, situated across the arc ABC. The area of the sector OABC is 4/3π and the length of the arc ABC is 2/3π.

Find the value of r and θ.

Thanks for your help!
