Question 7
The area of the circle that can be inscribed in a square of side 6 cm is
(A) $36\pi c{m}^2$
(B) $18\pi c{m}^2$
(C) $12\pi c{m}^2$
(D) $9\pi c{m}^2$

Answer 1

Given side of square = 6cm

$\therefore$ Diameter of a circle (d) = Side of square = 6cm

$\therefore$ Radius of a circle (r) $=\frac{d}{2}=\frac{6}{2}=3cm$

Area of circle $=\pi (r{)}^2$

$=\pi (3{)}^2=9\pi c{m}^2$
