And, there are two conditions for a plane to form: 1) Three non-collinear points, as R, S and U do not lie on the same line so they are non-collinear. And 2) A straight line and a point that does nt lie on the staright line. Here, the straight line is RS and the point is U.</span>
Answer:
If radius of circle = 1, the shaded sector area is calculated by:
A = pi x radius^2 x (136 x 2)/360 = 3.14 x 1^2 x 272/360 =2.37
Hope this helps!
