1. Which equation best describes the relationship among the segments formed by the intersecting chords? 

Options- PT*QT*=RT*ST,  PT/QT=RT/ST,  PT+QT=RT+ST,  PT*PQ=RT*RS

2. What is the length of an arc with a central angle of 2/3(pi symbol) radians and a radius of 24cm? Use 3.14 for pi. Round to the nearest hundredth, if necessary. Answer in decimal form.

1. PT*QT*= RT*ST

 

2.   arc length  =  r * theta   =   24 * (2pi/3)   =  16 pi  =  16 * 3.14  = 50.24 cm
