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: 255 sq cm
Explanation:
Diameter of the circle = 13 + 5 = 18 cm
∴ Radius = Diameter/2 =18/2 = 9 cm
Area of the circle = πr2 = (22/7) x 92
= (22 x 81)/9
= 1782/7
= 254.57 sq cm
= 255 sq cm
