Correct Answerसही उत्तर
C. 112 cm²C. 112 सेमी²
Explanationव्याख्या
Square diagonal = 14√2 cm, which is the circle diameter.
Radius = 7√2 cm.
Circle area = 22
7 × (7√2)² = 308 cm².
Square area = 196 cm².
Required area = 308 − 196 = 112 cm².
वर्ग का विकर्ण = 14√2 सेमी, जो वृत्त का व्यास है।
त्रिज्या = 7√2 सेमी।
वृत्त का क्षेत्रफल = 308 सेमी² और वर्ग का क्षेत्रफल = 196 सेमी²।
अंतर = 112 सेमी²। ---
