Answer: 12 for the main square
Step-by-step explanation:
take the 4 and the 3 and multiply it, makes 12. you see how each stair is 6 inches and there is 3 full steps which makes it 1.50 feet. 12 x 1.50 is 18. that makes your main square. I'm sorry but I cant really help you with the steps but that was also confusing to me.

Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll assume the graphed function comes from:

So this is the equation of a parabola that opens upward and whose vertex lies on the point:

The graph of this function is shown below. Which is true regarding the graphed function f(x)?
- It is true that the domain is the set of all real numbers because this is a polynomial function.
- It is true that the range is the set of all real numbers such that y ≥ 5
- It is true that this parabola opens upward
- It is true that it doesn't cut the x-axis
Answer
≈75.36ft
Step-by-step explanation:
C=2πr
C=24π
C≈75.3982
Or, if you substitute π with 3.14 instead:
C=2(3.14)r
C=6.28(12)
C=75.36
Hope this helps! Tell me if you have any questions!
