Alright let’s see the question
Answer:

Step-by-step explanation:
Once we know the diameter of the circle, we can figure out the problem.
The diameter of the circle = The diagonal of the rectangle inscribed in the circle
To find the diagonal of the rectangle, we can use a formula.

The width is 10 cm and the length is 12 cm.


The diagonal of the rectangle inscribed in the circle is 15.62 cm.
The diameter of the circle is 15.62 cm.
Find the area of the whole circle.

The
is the radius of the circle, to find radius from diameter we can divide the value by 2.



Let’s find the area now.


Find the area of rectangle.

Length × Width.


Subtract the area of the whole circle with the area of rectangle to find area of shaded part.


Angles ABD and DBC are supplementary. They are also a linear pair because they share a ray. Supplementary angles add up to equal 180, as do linear pairs. Therefore, from our picture, 7x + x - 4 = 180. 8x = 184. Therefore, x = 157. 157-4 = ∠DBC, so ∠DBC = 153.
