You will be given the dimensions of a race track. The diameters of the circle and the width of the rectangle = 90 mįinding the Area and Perimeter of a TrackĪfter completing this chapter, you will be able to use the concepts you learned to answer the questions in the STEAM Video Performance Task.
The perimeter of the track is the two circumferences of the circumferences. Length of the outer running track = 488 mĢ. Therefore the length of the remaining portion = 400-180 = 220 mĬircumference of the two remaining semi-circular portions = πr + πr = 2πrĪrea of the track = 2 x 90 x 14 +3.14 x (49) x (49) – (35) x (35) The total length of the two straight portions = 90 + 90 = 180 The inside perimeter of the track = 400 m The distance around each semicircle = 90π + 320ġ. The distance around each semicircle on the 400-meter, innermost lane = 488 mĢ. How does the width of the rectangle, 63.7 meters, compare to the distance around each semicircle? Explain.ġ. What is the distance around each semicircle on the 400-meter, innermost lane?Ģ. The dimensions of the rectangle formed by the innermost lane are shown. A track consists of a rectangle and two semicircles. Watch the STEAM Video “Track and Field.” Then answer the following questions.ġ. How can competitors run in different lanes and have the same finish line? Geometric Shapes and Angles STEAM Video/Performance Taskĭifferent lanes on a race track have different lengths.
