Mathematics
1 answer:
Ostrovityanka [42]2 years ago
4 0

Answer:

3 pi

Step-by-step explanation:

We already know that the sum of the angles adds up to 360.

Therefore we get 73+ 104+ 43 + x = 360, where x = 140

arc length = \frac{angle}{360} * (2\pi r)

were the angle is 140 and r = 4. The radius was given.

Hope this helps.
