A high school track is shaped as a rectangle with a half circle on either side. (85yd)(25yd) Jasmine plans on running three laps. How many yards will Jasmine run? Use 3.14 for pie. 248.5 yd 490.5 yd 725.5 yd 745.5 yd

Respuesta :

Answer:

745.5 yd

Step-by-step explanation:

  • Picture is attached of the given information
  • We need to add 85 yard twice and also we need circumference of the circle at the ends to find the complete length of track.
  • Circumference of circle is 'C = pi*d'. Diameter is 25 yd hence the circumference:

                                 C = 3.14 * 25 = 78.5

  • Now total length of track = Circumference + 2*78 = 78.5 +170 = 248.5 yd
  • Since Jasmine covers 3 laps so the yards that she will cover is:

                   1 lap = 248.5

                  3 lap = 3*248.5 = 745.5
