radius off. A greater is given by our is because 22 times off the for Poland, where the focal and given we have is 800 millimeter, which is equal to 0.8 meters and multiplying tuba two by 0.8 meters gives us 1.6. So the radio's off. Courage we have is 1.6 meters end off the problem. Thank you for watching.
