Question

30) In the figure ABCD is a square of side 10cm. Find the area of shaded region.​

Answer 1

Answer:

60.71 cm²

Step-by-step explanation:

Find the area of the square:

Area = Length x Length

Area = 10 x 10

Area = 100 cm²

Find the area of the semicircle:

Area = 1/2 πr²

Area = 1/2 π (10 ÷ 2)²

Area = 39.29 cm²

Find the area of the shaded region:

Shaded Region = Area of the square - Area of the semicircle

Shaded Region = 100 - 39.29

Shaded Region = 60.71 cm²

Answer: 60.71 cm²
