The Amazing Circle

Diameter is 2cm

So, Radius will be 2÷2 = 1cm

Area = pi × radius × radius

Area = 3.14 × 1 × 1 = 3.14

Formula for finding area of a circle: A=piR square . Known is the diameter which is 2 cm. so 3.1416(pi) x 1(radius)= 3.14 elementary. You can solve this mentally .

Since diameter is 2 Cm so radius is 1 Cm.with formula area of circle pia r2 = 3.14 X 1 square that is 3.14 Ans K.K.GARg,India

A=πr2 According to question " r " = d/2 =2/2=1 so ; A = 3.14 X 1X1= 3.14

area=pie r squared

diameter=2cm Therefore, radius=1/2 diameter =1/2 2 =1 cm Area of circle=pi * radius^{2} =3.14 *1^{2} =3.14 *1 =3.14cm^{2}
