Circumference of the circle
cm
i.e., 
i.e., 
Area of the circle is given by




Therefore, the area of the circle is:

The density is 4, and the mass is 12.
So we just plug this into the equation
d = m/v
4 = 12/v
We know that the volume must be 3 to make the equation true, because 12/4 = 3.
Therefore, the answer is F. 3 cm ^3
i believe it's y-intercept!
to be honest i was never taught why it was the y-intercept, i was just told that it was. hope this helps!
Answer:
ha me
Step-by-step explanation:
It's a. 3.
because
3+6x=21
6x=18
x=3.
