Answer:
Maybe 12.56
Step-by-step explanation:
Well, the question is a bit hard to read, but I assume the radius is equal to 2?
The formula for the area of a circle is п*r*r
The number п is equal to 3.14
so п*2*2 = 3.14*4 = 12.56
Though if the radius is not 2, try to use that formula and if you cant get it please let me know in the comments
Well if the first point is (-2, 1) and the slope is three than the other point would be (-1, 4)
