Dorothy ran 6 times around a circular track that has a diameter of 47 m. Approximately how far did she run? Use π = 3.14 and round your answer to the nearest meter.

    First calulate circumference of circular track with 2(pi)r Total distance run= 6 times the circumference =6x2(pi)r =885.48 metres =nearest to 885 metres..I presume so.. @UmmmHELP ...what do you think?

    Yeah here is what I did (3.14) * (47 meters) = 148.52 meters ran around 6 times so then 148.52 meters * 6 = 891.12 meters
