4. The circumference of (distance around) a circle is e times the disameter, or C- nd. A side of the square is the diameter of each half circle. (Circumference pi x diameter) In your answer to question 1, you gave the number of complete circles included in the track Use this answer and C- nd to find the approximate length of the circular part of the track to the nearest tenth of a foot. Use 14 forn and show your work Since there is 1 complete circle on the track, the length of the circular part of the track is feet S. Find the approsimate length of the track (to the nearest tenth), including the straight and crcular sections The approximate length of the track feet
