Robert runs around a circular track with radius 2.13 m. He can run one lap in 1.31 s. What is Robert's tangential velocity? (HINT: Solve for circumference firstl) square

## Step 1<br />The problem involves calculating the tangential velocity of Robert, which is the speed at which he is running around the circular track. The formula for tangential velocity is given by:<br />### \(v = \frac{2\pi r}{T}\)<br />where \(v\) is the tangential velocity, \(r\) is the radius of the circular path, and \(T\) is the time taken to complete one lap.<br /><br />## Step 2<br />In this problem, the radius \(r\) is given as 2.13 m and the time \(T\) is given as 1.31 s.<br /><br />## Step 3<br />Substitute the given values into the formula to calculate the tangential velocity.
