Question

If r=1 and 0 = 7pi/4 what is the approximate arc length?

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

data:

r = 1

θ = 7π / 4

Step 02:

arc length:

$arc\text{ length =}\theta\text{ r = }\frac{7\pi}{4}*1=\text{ 5.498}$

The answer is:

arc length = 5.498 units
