Answer:
28.26 in
Step-by-step explanation:
Radius = (1/2) diameter
Radius = (1/2)(9)
Radius = 4.5 in
Circumference = 2πr
Circumference = 2(3.14)(4.5)
Circumference = 28.26 in
Take the 16 swimming caps and divide them by the s swimmers to get the expression 16/s.
Angle m and n are 76 P Q and R are 60
