Question
Determine the area of the largest
circle that can be inscribed inside a square with a side length of 28 cm? (Use π = 22/7)Solution
ATQ, For size of the circle to be maximum, diameter of the circle = length of each side of the square So, diameter of circle = 28 cm Therefore, radius of the circle = 28/2 = 14 cm Area of the circle= π × r × r = (22/7) × 14 × 14 = 616 cm2
