A.T.Q.

 \bold{Circumference \:  \:  of \:  \:  the  \:  \: circle = 1232 }\\  \\  \bold{\Rightarrow \:  2 \: \pi \: r \:  = 1232 } \\  \\  \bold{\Rightarrow \: 2 \times  \frac{22}{7} \times r = 1232 } \\  \\  \bold{\Rightarrow \: \frac{22}{7}  \times r =  \frac{1232}{2} } \\  \\ \bold{\Rightarrow \: \frac{22}{7}  \times r = 616} \\  \\  \bold{\Rightarrow \: r = 616 \times  \frac{7}{22} } \\  \\  \bold{\Rightarrow \: r = 28 \times 7} \\  \\ \bold{  \therefore \:  \: r = 196} \\  \\

 \bold{ \therefore \:  \: Radius = 196} \\  \\  \bold{ \therefore \:  \: Diameter = 2 \times Radius } \\  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \bold{= 2  \times 196} \\  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \bold{ = 392}</p><p>
