The area would be cm²
Step-by-step explanation:
Consider O is the center of the circle and A, P and B are points of the circumference of the circle. ( shown in below diagram )
Given,
The radius of the circle, r = 21 cm,
Angle made by arc AB in circle, = 60°,
Thus, the area of the sector OAPB formed by the arc
= 231 cm²
Now, area of a triangle having adjacent sides and with included angle is,
So, the area of triangle OAB
Hence, the area of chord APB = Area of OAPB - area of triangle OAB
