b=3.1cm
Answer:
.
Step-by-step explanation:
The given expression is
It can be rewritten as
![2\left [\pi-\cos^{-1}\left(\frac{1}{\sqrt{2}}\right)\right]](https://tex.z-dn.net/?f=2%5Cleft%20%5B%5Cpi-%5Ccos%5E%7B-1%7D%5Cleft%28%5Cfrac%7B1%7D%7B%5Csqrt%7B2%7D%7D%5Cright%29%5Cright%5D)

Hence, the exact value of given expression is .
True.
The rational numbers include all the integers, plus all fractions, or terminating decimals and repeating decimals. ... All natural numbers, whole numbers, and integers are rationals, but not all rational numbers are natural numbers, whole numbers, or integers.
