Answer:
28.26 square inches
Step-by-step explanation:
Formula for area of a circle:

Radius is 3.

Use 3.14 for pi:

The area should be 28.26 square inches.
Rate of change = slope
slope = )y2 - y1) / (x2 - x1)
(0,-4)....x1 = 0 and y1 = -4 (pay attention to the negative sign when subbing)
(3,2)....x2 = 3 and y2 = 2
now we sub
slope(rate of change) = (2 - (-4) / (3 - 0) = (2 + 4) / 3 = 6/3 = 2 <==
