<u>Answer:</u>
The value of cos 45 degrees in simplified radical form is 0.70710 approximately.
<u>Solution:</u>
Given, Cos of angle 45 degrees.
We have to find the value of the Cos of 45 degrees in radical form.
From trigonometric ratios,
Cos of angle 45 degrees = cos 45 = 
Multiplying numerator and denominator with square root of 2
The value of square root of 2 is 1.414213
Hence, the value of Cos of angle 45 degrees is 0.70710 approximately

Answer:
Step-by-step explanation:
It is given that,
Mass of benzene, m = 0.1 L
Mass, m = 36.4 g
We know that, 1 L = 1000 cm³
0.1 L = 100 cm³
The density of an object is equal to its mass divided by its volume. So,
So, the density of benzene is 
.
