First, we've got to convert radians to degrees.
blank degrees = 4π/3 * (180/π)
= 240
So, the arc we are measuring is 240 degrees.
Now let's find the length of the arc.
The formula is θ/360 * 2πr
240/360 * 2 * (3.14) * 42
= 2/3 * 2 * 3.14 * 42
= 4/3 * 3.14 *42
= 12.56/3 *42
= 527.52/3
= 175. 84
The length of the arc is about 175.84 cm long.
