Pi=3.14
m=6 g=0.006 kg
r=5 cm =0.05 m
h=2 cm=0.02 m
volume_of_cone=pi*r^2*h/3 = 5.23599*10^-5=5.24E-5
p=m/v
p=(0.006/(5.24E-5))=1.14503817*10^-8=1.14503817e-8
Answer:
I think its the 1st one, but I'm not sure
Remember that transformation between Cartesian and polar system are:
x=r*cos(α)
y=r*sin(α)
From this we can conclude that:
r=√(x^2 + y^2)
Using trigonometry transformations we can write:
r=sin(2α) = 2sin(α)cos(α)
Now we can multiply both sides with r^2:
r^3 = 2(r*sin(α))*(r*cos(α))
Now using some replacements we can write:
(x^2 + y^2)^(3/2) = 2*x*y
Answer:
A
