A
B
P
AB = 12 ft
a
16 ft

AC = 4π ft

Step-by-step explanation:

The length of arc AC is calculated as

AC = circumference of circle × fraction of circle

∠ APC = 180° - 60° = 120° ( adjacent angles on a straight line sum to 180° )

diameter AB = 12 , so radius r = 12 ÷ 2 = 6 , then

AC = 2πr ×

     = 2π × 6 ×

     = 12π ×

     = 4π ft

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide
