Answer:
C = 60pi cm or approximately 188.4 cm
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
C = 2* pi * 30
C = 60 pi
We can approximate pi by 3.14
C is approximately 60*3.14 or 188.4
40.21/12.5
We would do this because the problem asks for unit rate
And and we need to find out the cost for one square foot
40.21/12.5 = 3.2168
We need to round this ANSWER and round it or else it will be incorrect
The answer would round to 3.22
Therefore, the answer is $3.22 per square foot
Answer:
8
Step-by-step explanation:
This can occur through a parabola that has zeroes at x = 3 and x = -3. There is no rate of change because the y values do not change at those points because they are both 0. Karly can be correct because that turning point can be a vertex of a parabola. The parabola's function would increase until it reaches it's highest point and then go back down again. In this way, Karly and Tucker can both be correct.
Hope this helps :)
