The area of circle Z is 641 ft.

Mathematics
1 answer:
levacccp [35]3 years ago
7 0

Answer:

I think  the radius would be 14.28ft

Step-by-step explanation:

Area of circle is pi r^2

Area of circle=641ft

so that means you have to divide 641/3.14 because the point of the question is finding the radius.

so 641/3.14=204.140127

then for the final step finding the square root which is about 14.28ft

that means the radius is 14.28ft.

Answer:

Formula to find height when given diameter and slanted height

\sqrt{s { }^{2} }  - r {}^{2}

First find the radius

24÷2=12

Next square the radius

12²=144

Next square the slanted height

20²=400

Now find the square root of both

\sqrt{400 - 144}

=16ft

<h2>Hello!</h2>

The answer is:

The correct option is the first option:  

y=-4x+64

<h2>Why?</h2>

To write the equation of the line in slope-interception  form we need to extract all the information that we need from the graphic.

We must remember that the slope-interception form of the lines is:

y=mx+b

Where,

y, is the function

m, is the slope of the line

x, is the variable

b, is the y-axis intercept

We can find the slope using the following formula:

m=\frac{ChangeInY}{ChangeInX}

Which is for this case:

m=\frac{64}{16}=4

As we can see from the graphic, the line is decresing, so the sign of the slope "m" will be negative, so:

m=-4

We can find the value of "b" seeing where the line intercepts the y-axis.

As we can see it intercept the y-axis at:  y=64

Then, now that we already know the value of "m" and "b", we can write the equation of the line:

y=mx+b=-4x+64\\y=-4x+64

So, the correct option is the first option:

y=-4x+64

Have a nice day!
