The formula for circumference:  C  =  pi · diameter.

                                                   C  =  pi · 28 feet

                                                   C  =  87.965 feet

 

Since PS is a diameter, arc(ST)  =  180o - 125o  =  55o

So, arc(ST), in feet, will be  (55/360) · 87.965 feet  =  13.4 feet

 

Arc(RPT)  =  360o - arc(RS) - arc(ST)  =  360o - 97o - 55o  =  208o

Arc(RPT, in feet, will be (208/360) · 87.965 feet  =  .........
