एक आयत की लम्बाई 15 सेमी. है, जो एक वृत्त के व्यास से 6 सेमी. कम है, इस वृत्त का क्षेत्रफल होगा :
Detailed Solution & Logic
Correct Answer:
346.5 cm\(^2\)
Solution
Length of rectangle = 15 cm
The length is 6 cm less than the diameter of the circle.
Diameter of circle = 15 + 6 = 21 cm
Radius of circle = 21/2 = 10.5 cm
Area of circle = $\pi r^2$
$= \frac{22}{7} \times 10.5 \times 10.5$
$= 346.5\text{ cm}^2$
Answer: 346.5 cm²
