If the circumference of a circle if 188.4cm what is the area, radius, diameter?

Question

Need some help?haha please?:)

Answer 1

serkel: rim length=188.4

=pi*diameter, so diameter=188.4/pi=59.96958263

radius=half diameter=29.98479131

area=pi*radius*radius

but, pi*radius=(rim length)/2=94.2

area=94.2*radius

=94.2*29.98479131

=2724,556341

Answer 2

Circumference=188.4 cm

or,2 pi r =188.4

or,r =188.4/2*pi

      =29.97 cm

Radius=29.97 cm

Diameter=(2*29.97) cm

             =59.94 cm

Area=pi*r^2

       =94.2*29.97  cm^2

       =2823.174  cm^2
