Answer: The area of shaded section is 491.07 cm²
Step-by-step explanation:
Given: Radius of the circle = 25 cm
Now as shown in figure the shaded region is a quadrant.
Therefore the central angle is 90°
Now as we know
Area of sector is given by
where r is radius and 
is central angle
So we have
Hence, the area of shaded section is 491.07 cm²

D. 52
Step-by-step explanation:
Add 85 and 45 to get 130.
6.2n-3.7n=130
Subtract 3.7 from 6.2
2.5n=130
divide 130 by 2.5 to find n
N=52
