The circumference of a circle is equal to the perimeter of a rectangle. The length and the breadth of the rectangle are 45 cm and 43 cm, respectively. What is the half the radius of the circle?
Correct Answer: Description for Correct answer:
According to the question,
\( \Large 2\pi r \)=2(45+43)=\( \Large 2\times 88 \)
=> r=\( \Large \frac{2\times 88 }{2\pi} \)
\( \Large \frac{1}{2}r \)=\( \Large \frac{2\times 88\times 7}{2\times 44} \)=14 cm.
