Find the area of a circle with diameter 12 cm.

luda_lava [24]

Answer:

113.04 cm.

Step-by-step explanation:

Step 1: <u>Formula/explain</u>

To find the area of a circle, multiply the radius by itself twice, then multiply the product pi.

$a=\pi r^2(3.14*radius*radius)$

Step 2: <u>Solve</u>

According to the word problem, the circle has a diameter of 12. This means it has a radius of 6.

Now, we plug the numbers into formula.

$\pi 6^2 (3.14*6*6)=113.04$

Step 3: <u>Conclude</u>

Therefore, the area of this circle is 113.04 cm.

PLEASE HELP I WILL MARK BRAINLIEST!<br> Question is in the image.

deff fn [24]

Answer:

8

Step-by-step explanation:

The interquartile range of a data set is the difference between the upper and lower quartiles.

First, put the values in order from least to greatest:

8, 9, 9, 9, 10, 11, 13, 15, 17, 18, 22

To find the upper quartile, we need to first find the median.

The median of this data set is 11, because it is in the middle of the values.

The upper quartile is the median of all the numbers to the left of 11.

The median of 8, 9, 9, 9, and 10 is 9, because it's in the middle.

So the upper quartile is 9.

The lower quartile is the same, but to the right of 11. The median of 13, 15, 17, 18, and 22 is 17 because it's in the middle.

Now, to find the interquartile range, find the difference between 18 and 9.

17 - 9 = 8

What is the inverse of <br><br> X^2-2x+3

schepotkina [342]

So you have x, then you square it to get x^2, then you minus 2x, then +3
The inverse is going backwards so you -3 then +2x then square root x
So you get square root x + 2x -3
I'm pretty sure this is right, sorry if I'm wrong.
