You want to use the circumference to make your life easier... 
The circumference of the track=  π * diameter or π * d
= (3.14) * (47 meters)
= 148.52 meters
Dorothy ran around the track 6 times so 
Distance Dorothy ran = 148.52 meters * 6
= 891.12 meters
Dorothy ran about 891 meters. 

PS. Its pi not pie, hehe.
