area:
4x4x3.14x12=602.88
Answer:
y = 52 - 8x
Step-by-step explanation:
If he painted for 3 hours at a rate of 8 square meters per hour, the area painted was:

If after 24 squared meters painted, there are still 28 left, the total area is:

The area still left to paint is initially 52 squared meters and decreases at a rate of 8 square meters per hour, the function that describes the relationship between the area left to paint (y) and number of hours (x) is:
y = 52 - 8x
Answer:
72
