Question
Calculate the perimeter of a square when the area of a
circle that circumscribes it is 486 square centimeters. (Assume π = 3 for calculations.)Solution
ATQ, Let radius of the circle is ‘r’ cm. So, πr 2 = 486 Or, r 2 = 162 Or, r = 9√2 So, diameter of circle = diagonal of square Or, √2 × side of square = 2 × 9√2 So, side of square = 18 Perimeter of square = 4 × side = 4 × 18 = 72 cm
