Correct Answer: 35 m
Solution : Given: The difference between the circumference and diameter of a circle is 150 m. Let the radius of the circle be $r$. Its diameter = $2r$ and its circumference is $2\pi r$. According to the question, $2\pi r\ –\ 2r=150$ ⇒ $2r(\frac{22}{7}-1)=150$ ⇒ $r\times(\frac{22-7}{7})=\frac{150}{2}$ ⇒ $r\times(\frac{15}{7})=75$ $\therefore r=35$ m Hence, the correct answer is 35 m.
