45 is exactly half of 90
that means 45 is 50% of 90.
Given that,
Radius of the circle, r = 8.91 cm
Angle, 
To find,
The area of minor sector.
Solution,
The formula for the area of minor sector is given by the formula as follows :

So, the area of the shaded sector is
.
Substitute the given number into the equation
Sum = 180(15-2)
Solve brackets
180(13)
Which is equal to 2340
So, the sum of interior angles is 2340 degrees
