Calculate the area of a circular disc whose diameter is 14 cm Share with your friends Share 0 Jainendra Kumar Sharma answered this Dear Student, Area of the circular disk is given by : πr2 Where r = radius and π = 3.14Given : Diameter = 14 cm So, Radius = 142=7 cmSo, area of the circular disk = πr2 =3.14×(7)2 =3.14×49 =153.86 cm2So, area of the circular disk = 153.86 cm2 Hope this information clears your doubts. Regards 1 View Full Answer Nandini Das Biswas answered this Area of circle = π r2 Therefore, area of the circular disc = 3.14159 multiplied by [14/2]2 = 3.14159 multiplied by 72 = 3.14159 multiplied by 49 = 21.99113 Ans = 21.99113 is the area of the circular disc. 1
