Answer:

Explanation:

5) Perimeter = 15 + 21 + 15 + 21 = 72 cm

6) diameter = 12 cm

Radius r = 12/2 = 6 cm

Circumference = 2πr

= 2 * 3.14 * 6

= 37.68 cm

8) Distance around the track = 2 *circumference of semi circle + 80 + 80

= circumference of circle + 80 + 80

= 2 * 3.14 * 10 + 80 +80

= 62.8 +80 +80

= 222.8 cm
