assuming we are finding the circumference of the outer circle or the path to find the length of the fence we start by combining the radius of the pool and the path width for the radius of the second circle around the first one. the circumference or C is equal to 2 x the radius or r you can also use the diameter or d, times for the circumference
To find the answer to this question, we need to plug in x=10 into the equation y = -63x + 825. y = -63(10) + 825 y = -630 + 825 y = 195 Thus, there will be 195 cans left after 10 days.
