Question

The figure below is made up of two intersecting circles. The points $A$ and $B$ lie on the circumference of the circles. The larger circle has centre $C$, $AC = BC = 16$ cm and $\angle ACB = 0.85$ radians.

Calculate the area of the shaded segment.
The smaller circle, with centre $D$, cuts the first circle at $A$ and $B$.
The radius of the smaller circle is $12$ cm.
Calculate, in radians, $\angle ADB$.
Calculate the perimeter of the sector $ADB$.

Accepted Answer
