Answer:4^2≈50.26548
Step-by-step explanation:
πr2.
Where r is the radius and π≈3.14 , the ratio of a circle's circumference to its diameter.
Plugging in 4 from the radius, we get.
42π
⇒16π inches.
This is our exact answer. Alternatively, we can plug in 3.14 for π to get.
50.26 inches.
5(6x+5)-2(4x-1) = 30x+25-8x+2 = 22x+27
Answer:
if those are variables they can equal anything you want like r=4 and p=2 r/p = 2
Step-by-step explanation:
Answer:
Third option

Step-by-step explanation:
In this case we must write a quadratic equation in the vertex form.
We have the vertice. (-1, 5)
We know that the vertex form for a quadratic equation is:
.
Where (h, k) is the vertex.
So if the vertex is (-1, 5), the equation sought is:


Therefore the answer is the Third option.
