Which of the following segments is a radius of OK?<br> ОА. АМТ<br> ОВ. Вт<br> Ос. AMR<br> O D. KM
FrozenT [24]

Answer:

A) TA

Step-by-step explanation:

A radius goes from the center of a circle to the outside edge.  

RP connects two points on the outside edge of the circle without going through the center.  This is not a radius.

TR connects two opposite points on the outside edge of the circle while going through the center.  This is a diameter, not a radius.

GP connects two opposite points on the outside edge of the circle while going through the center.  This is a diameter, not a radius.

TA connects the center of the circle to the outside edge.  This is a radius.
