The side of a square is 5 cm which is 13 cm less than the diameter of a circle. What is the approximate area of the circle?
Correct Answer: Description for Correct answer:
Diameter of the circle = 13 + 5 = 18cm
Radius =\( \Large \frac{Diameter}{2}=\frac{18}{2} \)=9 cm.
Area of the circle = \( \Large \pi r^{2}=\frac{22}{7}\times 9^{2} \)
= \( \Large \frac{22\times 81}{7}=\frac{1782}{7} \)=254.57 sq cm.
=255 sq cm.
