50 POINTS NEED HELP ASAP!!! What is the arc length of an arc with a central angle of 23π radians in a circle with a radius of 18 cm?

Enter your answer to the nearest whole centimeter in the box.

__cm

Answer 1

Use the general formula

• L=rØ
• L=2/3π(18)
• L=2(6)π
• L=12π
• L=38cm

Answer 2

• 38 cm

Explanation:

Arc length is:

• s = rθ, where r- radius and θ - central angle in radians
• s = 18*(2/3)π ≈ 38 cm
