What is the circumference of area=64pi mi^2

Mathematics
1 answer:
azamat3 years ago
4 0

Answer:

  16pi mi

Step-by-step explanation:

The smallest circumference for a given area is that of a circle with that area. The area is given by ...

  A = πr²

so we can find r as ...

  64π = πr²

  r = √64 = 8 . . . . miles

The circumference of this circle is ...

  C = 2πr = 2π·(8 mi) = 16π mi

The circumference of the area is at least 16π miles.

_____

If the shape is not constrained to a circle, the circumference can be anything you like.

Draw the graph of f(x) = (x − 1)2 − 2. Start by creating a table of ordered pairs for the function. Then plot the points from th

The attached graph represents the graph of f(x) = (x - 1)^2 - 2

<h3>How to plot the graph?</h3>

The equation is given as:

f(x) = (x - 1)^2 - 2

Next, we set x to -2, -1, 0, 1 and 2.

So, we have:

f(-2) = (-2 - 1)^2 - 2 = 7

f(-1) = (-1 - 1)^2 - 2 = 2

f(0) = (0 - 1)^2 - 2 = -1

f(1) = (1 - 1)^2 - 2 = -2

f(2) = (2 - 1)^2 - 2 = -1

This means that the table of values is

x      f(x)

-2    7

-1    2

0    -1

1     -2

2    -1

Next, we plot the above points and connect them.

See attachment for the graph of f(x) = (x - 1)^2 - 2
