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

Hello!
Since Trey pays a flat monthly $6 fee, we can subtract that from the total bill:
$12.27 - $6 = $6.72
That leaves us with a total of $6.72 paid for minutes. We are told that Trey is charged 8 cents per minute of usage. Using the information above, we can create the following equation:
$0.08 x (minutes) = $6.72
Now divide $0.08 from both sides of the equation and simplify:
x (minutes) =
minutes = 84
We have now proven that Trey was billed for 84 minutes.
I hope this helps!
