Answer 1

Answer:

44 is APD and 56 BQC of radius

Answer 2

Step-by-step explanation:

Given In fig., APD and BQC are semicircles of radius 7 cm. The area of shaded region (in cm)

• APD and BQC are semicircles
• We need to find the area of shaded region
• So all the sides = 14 cm
•        So Area of square – 2 (Area of semicircle)
•             (side)^2 – 2 (πr^2 / 2)
•             (14)^2 – 2 (22/7 x 7 x 7 /2 )
•              196 – 2 (77)
•                196 – 154
•                    42 cm^2
• Therefore area of shaded region will be 42 sq cm
