The area of a sector of a circle with a central angle of 3π/13 rad is 19 m2. Find the radius of the circle.
+36923 The area of the WHOLE circle is the area of the central angle of 2pi
Let's set up a ratio 2pi / (3pi/13) = x / 19
and solve for 'x' = 2pi / (3pi/13) x 19 = 26 / 3 x 19 = 494 / 3 =164 2/3 m^2
