The difference between the circumference and radius of a circle is 37cm. The area of the circle is:

🧠 Explanation:

Circumference minus radius = 37 cm: $2pi r - r = 37$. Solve: $r(2pi - 1) = 37$, $r approx 7$. Area = $pi r^2 approx 154 , text{cm}^2$. Studying this highlights geometry, a key topic in mathematics. It ensures accurate calculations, with implications for engineering and design.
