Answer:
Perimeter = 101.496 cm
Step-by-step explanation:
draw line from point C that is perpendicular to line AD. Call that point E.
tan 43° = 16.7/ED
0.9325 = 16.7/ED
ED = 17.909 cm
sin 43° = 16.7/CD
0.6820 = 16.7/CD
CD = 24.487 cm
Perimeter = AB + BC + CD + ED + AE
Perimeter = 16.7 + 21.2 + 24.487 + 17.909 + 21.2 = 101.496 cm
Circumference of whole circle =
360÷20=18
hence length of arc = 1/3 pi
