The area of circle is equal to

assume

substitute

Remember that the area of a circle subtends a central angle of 360 degrees

so

using proportion Find out the area of a sector with a central angle of 68.90 degrees

Let

x -----> the area of a sector

step 2

Find the area of the isosceles triangle

Applying the law of sines

The area is equal to

we have

substitute
