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
.
Hello,
x=r cos t
y=r sin t
x²+y²=r²
r=4 cos t
r=4x/r==>x²+y²=4x
==>(x-2)²+y²=4 (a circle center (2,0),radius 2)
