Homework Help: Math

I am supposed to find the area of the shaded section of a circle. The circle is cut with two radi with an angle of 60 degrees. Then where the radi touch the circle another line is drawn to connect them. The triangle and the small section between the triangle and the edge of the circle are the shaded areas. It also tells me that the unshaded area of the circle is 10 m.

I am not sure how to find all of the shaded area. Please help.

If the pie shaped wedge is shaded, then it has an area of 1/6 the area of the circle.

As I read, 10m^2=arecircle-shaded pie wedge

shaded area=10m^2-area circle

But the shaded area is 1/6 of the circle
shaded area=10-5shaded area
shaded area=10/6 m^2
