Answer:
feet, or 14.14 feet
Step-by-step explanation:
Use the arc length formula:
s = rθ
To use the formula, we have to convert the central angle to radians.
90° is equivalent to radians, so plug this and the radius into the formula:
s = rθ
s = (9)()
s =
So, the length of the arc is feet, or approximately 14.14 feet
I think the teacher would probably pick two boys and one girl
(22 + 15.50 + 2.75) 15
(22 * 15) + (15.50 * 15) + (2.75 * 15)
