The endpoints of a diameter of a circle are A(3,1) and B(9,9). Find the area of the circle in terms of pie

andrey2020 [161]

Answer:

The answer is $25\pi$ units squared.

Step-by-step explanation:

If we find the diameter, we can find the radius by halving the diameter.

We can find the diameter by using the endpoints of the diameter.

The distance formula will give us the length between (3,1) and (9,9).

The distance formula is $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ .

The distance between the $x$ 's is 9-3=6.

The distance between the $y$ 's is 9-1=8.

The distance between the points is given by $\sqrt{6^2+8^2}=\sqrt{36+64}=\sqrt{100}=10$ .

The radius is therefore $\frac{10}{2}=5$ .

We are asked to find the area of this circle.

The formula for finding the area of a circle is $\pi r^2$ .

Since the radius is $5$ , then the area in terms of $\pi$ ,(pi), is $\pi (5)^2=\pi (25)$ .

The answer is $25\pi$ units squared.

What is the correct answer?

Minchanka [31]

67.38 degrees

To find this, follow the steps below:

cos (B) = 5/13
cos -1 (cos(B)) = cos-1 (5/13)
The cos-1 and cos cancel each other out.

B = cos-1 (5/13)
B = 67.38

Hope this helps!

What is the equation of a line, in point-slope form, that passes through (−2, −6) and has a slope of 13 ?

Sav [38]

It is the 3rd answer, y+6= 13(x+2) since the the point slope formula is
y-y1 = m(x-x1)

you plug the y-value of the coordinate point into y1 and you plug the x-value of the coordinate into x1. You plug the slope into m.

What is 4x - 1 = 3x + 10 ?

AfilCa [17]

Answer:

x=11

Step-by-step explanation:

first add 1 to both sides and the -1 will cancel out. Your left with 4x=3x+11.

Then subtract 3x from both sides and you will be left with. x=11
