हल- चाप की लंबाई, l = 37.4cm

तथा कोण    \theta = 60 = 60 \times  \frac{\pi}{180} रेडियन =  \frac{\pi}{3} रेडियन

अतः , वृत्त की त्रिज्या  \:  \:  \:  \:  \frac{l}{ \theta}


 =  \frac{37.4 \times 3}{\pi} \\  \\   \\  \\  =  \frac{37.4 \times 3 \times 7}{22}  \\  \\  \\  \\  = 35.7cm

Length = 37.4 cm
Angle = 60°.
 = 60 \times  \frac{\pi}{180}  \: rad \\  =  \frac{\pi}{3} radian
Radius of circle = length/ Angle
 =  \frac{37.4}{ \frac{\pi}{3} }  \\  =  \frac{37.4 \times 3}{\pi}  \\  =  \frac{37.4 \times 3}{3.14}  \\  = 35.73
Hence Radius = 35.73 cm
