I don't know the questions you're working on. But I can tell you that
the formula (or equation) in your question doesn't look right to me.
-- If you know the circle's radius, then the circle's area is (pi) x (radius)².
-- If you know the circle's diameter, then the circle's area is (pi/4) x (diameter)².
Yes bc since 2x2=4 you just add the x to it
Answer:
Step-by-step explanation:
y = mx + b
we can see the slope is down hill, so it's negative
when the X is zero then it's 2
b = 2
slope is rise over run 2/3
y = -2/3x + 2
the slope is -2/3 (note the negative)
the y intercept is 2
