Question

97 π cm, 27,5cm , √5/3cm, 3/5cm

Answer 1

Explanation:

Note that

`(√(5))/(3)=(5√(5))/(15)\\(3)/(5)=(9)/(15)`

Since

`(5√(5))=125 > 81 = 9^2, \text{ then }\\(5√(5))/(15) >(9)/(15)`

So

`(3)/(5) < (√(5))/(3)`

Now clearly

`(√(5))/(3) < 1 < 27, 5 < 97 < 97\pi`

Therefore

`(3)/(5) < (√(5))/(3) < 27,5 < 97\pi`
