Suppose a wheel with radius 16 cm rolls in a straight line over a flat surface rotating a total of 5 radians. How far did the wheel travel?

Answer: 80cm

Step-by-step explanation:

Given:

Radius r = 16cm

Radial distance x = 5 radians

Radian is a measure of angles.

1 radian = 180°/π

To convert radial distance to linear distance

Linear distance = radial distance * radius

d = xr

d = 5 * 16cm

d = 80cm
