Identify the diameter of Q given that a= 169 pie in2

Kaylis [27]

Answer:

the diameter will be D=26 in.

Step-by-step explanation:

The area of a circle is given by:

$A=\pi R^{2}$ (1)

Where:

A is the area
R is the radius of the circle

Now, we know that A = 169 π in²

So, we just need to use equation 1 to find R.

$169\pi = \pi R^{2}$

$R=\sqrt{169}$

$R=13 \: in$

Therefore, the diameter will be D=2*R=26 in.

I hope it helps you!

What is the value of k(-6)<br> Please help!!!

velikii [3]

Answer:

Step-by-step explanation:

This is a piecewise function.

Since the value being asked to evaluate is -6, choose the part of the function that is applicable.

You would focus on $x\geq -6$ since you were given a -6 to evaluate.

Then use the expression that describes the function at that location.

$x^{2} - 1$

Plug in your value of -6

$(-6)^{2}-1\\ 36-1\\35$
