Answer:

area = 81π in² (or ≈ 254.47 in²)

Step-by-step explanation:

The formula for an area of a circle is area = πr².

You are given the diameter, which is 18 in.

diameter = radius (2)

So to get radius, divide the diameter in half:

18/2 = 9.

Now that we have the radius, put that back into the formula for the area of a circle:

area= π9²

Then, solve for the 9², which will be 81 and put it back into the formula.

area = 81π in²

If you need to get rid of the π, the answer will be about 254.47 in²

How can I solve number 4 and 6?

SOVA2 [1]

4. Here you would use the Pythagorean Theorem. a² + b² = c²
In this case a and b are the same, so : a² + a² = c² would also work.
a = 5√2 so: (5√2)² + (5√2)² = c²
Do you know where to go from here?

What is the slope of a line that contains the points (12,17) and (-8,-17)

professor190 [17]

$\frac{y2 - y1}{x2 - x1}$
$\frac{ - 17 - 17}{ - 8 - 12} = \frac{ - 34}{ - 20} = \frac{17}{10}$
Alternative forms:
$1 \frac{7}{10} \: or \: 1.7$
Slope: 17/10
Equation : y= 17/10x

-x = -6 <br> please help me

Rasek [7]

Answer:

The answer would be positive 6

Step-by-step explanation:

I know it is -6 because when you solve this you do...

-x = -6

Divide both sides by -6

-x/-6 = -6/-6

the answer would be 6

because a negative divided by a negative is a positive.

Hope this helps have a great day! :)
