A)
127 cm?
B)
2471 cm2
C)
3671 cm2
D)
7271 cm2

Answer 1

C is the answer to this question explanation: Area of square = 144 cm2, which means each side is √144 = 12 cm

Since the circle is inscribed in the square, the diameter is 12, so the radius is 6cm.

Area of circle = πr2 = π * 62 = 36π cm2, which is your answer :)
