a track is in the shape of a rectangle and two semicircles . the rectangle is 4 yards by 10 yards to the nearest yard what is the perimeter if the track?
The perimeter = the sum of the sides. The two ends are semicircles with a diameter of 4 yds. Add two semicircles and you have a complete circle.
The formula for the perimeter or circumference of a circle is:C=d%2Api, where c=circumference, d=diameter, and pi is approximatley 3.14. Therefore the ends have a perimeter of:
C=4%2A3.14
C=12.56 and that to the two lengths
P=12.56%2B10%2B10
highlight%28P=33yds%29
Happy Calculating!!!
