Answer 1

Answer:

Area of shaded area = 42 cm

छायांकित क्षेत्र का क्षेत्रफल = 42 सेमी

Step-by-step explanation:

Area of ABCD = 14cm × 14cm

= 196 cm²

Diameter of circle = 14 cm

Radius = d/2 = 7 cm

Area of 1 semicircle = 1/2 (πr²)

Area of 2 semicircle = 2×1/2 (πr²)

= (πr²)

= ( 22/7 × 7 × 7 ) cm²

= ( 22 × 7 ) cm²

= 154 cm²

Area of shaded part = 196 cm² - 154 cm²

= 42 cm²

ABCD का क्षेत्रफल = 14 सेमी × 14 सेमी

= 196 सेमी²

वृत्त का व्यास = 14 सेमी

त्रिज्या = d/2 = 7 सेमी

1 अर्धवृत्त का क्षेत्रफल = 1/2 (πr²)

2 अर्धवृत्त का क्षेत्रफल = 2 × 1/2 (πr²)

= (πr²)

= (22/7 × 7 × 7) सेमी²

= ( 22×7 ) सेमी²

= 154 सेमी²

छायांकित भाग का क्षेत्रफल

= 196 सेमी² - 154 सेमी²

= 42 सेमी²
