Answer:
18.85
Step-by-step explanation:
The area of a circle is A= pi × r² (r being the radius)
The radius is half the diamter so the radius would be 6
Plug 6 into the equation for the radius
A = pi × 6²
A = pi ×36
A= 18.85
Hey there!
We can see that the y-intercept is 6, or (0, 6), because when x is equal to 0, that is the y-intercept.
