Answer:
114 cm²
Step-by-step explanation:
Area of shaded region
= area of circle -area of square

Given that radius= 10cm, r= 10cm.

Let the length of a side of the square be x cm.
Applying Pythagoras Theorem,
10² +10²= x²
100 +100= x²
x²= 200

Area of square
= x²
= 200cm²
Area of shaded region
= 3.14(10²) -200
= 3.14(100) -200
= 314 -200
= 114 cm²
