Diameter=16 so divide by 2 to find radius
16/2=8=r

area of circle= pi*r^2

area of circle= pi*8^2

area of circle=64pi

now either leave it as an exact answer (64pi u^2) or convert it to a decimal and then round

201.06192983

round to nearest tenth= 201.1 u^2
or round to the nearest hundreth=201.06 u^2

What is the distance between (1, -4) and (1, 18

Annette [7]

<h3>Answer: 22 units</h3>

=====================================================

Explanation:

You can use the distance formula

$d = \sqrt{ (x_1-x_2)^2 + (y_1-y_2)^2}\\\\d = \sqrt{ (1-1)^2 + (-4-18)^2}\\\\d = \sqrt{ (0)^2 + (-22)^2}\\\\d = \sqrt{ 22^2}\\\\d = 22\\\\$

----------------

A shorter method is to subtract the y coordinates and apply absolute value

So either |-4-18| = |-22| = 22

Or, |18 - (-4)| = |18+4| = |22| = 22

This method only works because the x coordinates are the same. We can also use this method if the y coordinates were the same with the x coordinates being different.

Which of the following is not equivalent to 1?

cluponka [151]

Answer:

Step-by-step explanation:

This is because You would still have the Y value as the answer. When you raise a function to the 0 power you will ultimately get on. In this only the coefficient is being raised rather than the whole system.

What is the sum of (–2.1x + 3.7) and (5 + 4.9x)?

adoni [48]

Combine like-terms
-2.1x and 4.9x = 2.8x
3.7 and 5 = 8.7
2.8x + 8.7 is your final answer.
