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?


A) 245 sq cm

B) 235 sq cm

C) 265 sq cm

D) 255 sq cm

Correct Answer:
D) 255 sq cm

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.
