In a circle with a radius of 6 m, an arc is intercepted by a central angle of 7π/4 radians.

What is the arc length?

Use 3.14 for π .

2 answers

arc length = π r Ø
where r is the radius, and Ø is the central angle measured in radians

You have all the data.
actually, arc length = rØ

the whole circle has circumference 2πr.
