Question

What is the length of an arc with a central angle of 54π radians and a radius of 34 cm?

Use 3.14 for pi. Round to the nearest hundredth, if necessary.

Enter your answer as a decimal

Answer 1

If you are to solve for the central angle, 5pi/4, the answer would be 133.45. This answer is obtained using the strategy posted above.

Explanation:

Answer 2

The formula in solving the length of an arc is shown below:
Length of an Arc = 2pi*r (central angle/360°)
Central angle = 54pi * (180°/pi)
r = 34 cm

Solving for an arc length"
Arc length = 2*3.14*34((54*180)/360)
Arc length = 5,765.04 cm

The answer is 5,765.04 cm.
