Given the diameter of the circle =DF=12 cm

We have the area of the circle formula =pir^2,where the value of pi=3.142 and r is the radius of the circle.

r=12/2 cm=6 cm

Area =3.14*6^2 =36*3.142 =113.1 cm^2

Note:None of the option are matching.Please be sure whether it is asking for the area or the radius of the circle.

If it is radius of the circle then the radius =6 cm

and if it area then it is 113.1 cm^2.
