Answer:
![\pi +3 >2\pi -\sqrt{9}>\frac{\pi }{2}](https://tex.z-dn.net/?f=%5Cpi%20%2B3%20%3E2%5Cpi%20-%5Csqrt%7B9%7D%3E%5Cfrac%7B%5Cpi%20%7D%7B2%7D)
Step-by-step explanation:
![Lets\ take\ \pi 's\ approximate\ value\ as\ 3.14159\\Hence,\\ \pi +3\\=3.14159+3\\=6.14159\\2\pi -\sqrt{9} \\=2*3.14159-3\\=6.28318-3\\=3.28318\\\frac{\pi }{2} \\=1.570795\\](https://tex.z-dn.net/?f=Lets%5C%20take%5C%20%5Cpi%20%27s%5C%20approximate%5C%20value%5C%20as%5C%203.14159%5C%5CHence%2C%5C%5C%20%5Cpi%20%2B3%5C%5C%3D3.14159%2B3%5C%5C%3D6.14159%5C%5C2%5Cpi%20-%5Csqrt%7B9%7D%20%5C%5C%3D2%2A3.14159-3%5C%5C%3D6.28318-3%5C%5C%3D3.28318%5C%5C%5Cfrac%7B%5Cpi%20%7D%7B2%7D%20%5C%5C%3D1.570795%5C%5C)
![As\ we\ can\ see\ that,\\6.14159>3.28318>1.570795,\\Their\ corresponding\ values\ are\ also\ in\ the same\ order:\\\pi +3 >2\pi -\sqrt{9}>\frac{\pi }{2}](https://tex.z-dn.net/?f=As%5C%20we%5C%20can%5C%20see%5C%20that%2C%5C%5C6.14159%3E3.28318%3E1.570795%2C%5C%5CTheir%5C%20corresponding%5C%20values%5C%20are%5C%20also%5C%20in%5C%20the%20same%5C%20order%3A%5C%5C%5Cpi%20%2B3%20%3E2%5Cpi%20-%5Csqrt%7B9%7D%3E%5Cfrac%7B%5Cpi%20%7D%7B2%7D)
The answer is 22 hope this helps
