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.

Answer 1

The length of the arc is calculated by multiplying the ratio of the given central angle to the whole revolution by the circumference.
Length of the arc = (54π/2π)(π)(2)(34)
Length of arc = 1836π cm
Using π = 3.14, the answer then becomes 5767.96 cm.
