Question

The angular velocity of a point on a circle with radius of 13 feet is 14pi radians per second. Find the speed of the point on the circle.

Answer 1

Given:

The angular velocity of a point on a circle with radius of 13 feet is 14pi radians per second.

Required:

Find the speed of the point on the circle.

Explanation:

The speed is the angular in rad/sec times times the radius

$\begin{gathered} =14\times\pi\times13 \\ =182\times\pi \\ =571.48 \end{gathered}$

Answer:

Hence, option
