Question
Given a circle with a diameter of 56 cm, let the area of
the circle be represented as “x” sq cm and the circumference as “ y” cm. Calculate the value of x − y .Solution
Radius of the circle = 56/2 = 28 cm Area of a circle = 22/7 x 28 x 28 = 2464 cm2 Circumference of a circle = 2 x 22/7 x 28 = 176 cm Required value = 2464 - 176 = 2288 Hence, option c.
