What is the area of the remaining portion of a circle of radius 14 cm when a square with maximum possible area inscribed in it is removed from it? (Use π= 22/7)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 224 cm2.
Areacircle = πr2 = 22/7 × 142 = 22/7 × 196 = 22 × 28 = 616 cm2
Radius = 14 cm ⇒ Diameter = 2r = 28 cm
Diagonal of square = s2 =
s = 28/ = 14
Areasquare = s2 = (14)2 = 196 × 2 = 392 cm2
Remaining Area = Areacircle − Areasquare = 616 − 392 = 224 cm2
