Question

In figure, ABCD is a square of side 14 cm. Semi-circles are drawn with each side of square as diameter. Find the area of the shaded region.
​

Answer 1

Answer:

here is ur answer

Step-by-step explanation:

area of shaded region

=area of square -4×area of semicircle

${14}^{2} - \pi {7}^{2}$

=196-3.14×49

=196-154

=42 units sq

Answer 2

Answer:

84 cm2

Step-by-step explanation:

Area of 1 segment

= area of sector –area of triangle

=( 90˚/360˚)πr2 – ½ x7x7

=1/4x22/7x72 – ½ x7x7

= 14cm2

Area of 8 segments = 8x14= 112 cm2

Area of the shaded region = 14x14-112

= 196-112 = 84cm2

(each petal is divided into 2 segments)
