The radius of a circle is 9 feet. What is the length of a 90° arc?
1 answer:
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
