Answer:

6\pi, 6pi

Step-by-step explanation:

The area of the full circle would be \pi *4^{2}, which is 16\pi

A full circle is 360 degrees. Since we are only taking a part of that, 135, we would put it in a fraction. \frac{135}{360}

Last, multiply 16pi and 135/360 since we are taking a part of 16pi.

16\pi *\frac{135}{360}

\frac{2160\pi}{360}

6\pi

QUESTION 1

The given circle has equation:

x^2+y^2=16

We can rewrite to obtain;

(x-0)^2+(y-0)^2=4^2

This is equation is now in the form;

(x-h)^2+(y-k)^2=r^2

Where (h,k)=(0,0) is the center of the circle and r=4 is the radius.

QUESTION 2

The center of the circle is at (1,1) and passes through the point (4,5).

The radius of this circle is given by;

r=\sqrt{(4-1)^2+(5-1)^2}

r=\sqrt{(3)^2+(4)^2}

r=\sqrt{9+16}

r=\sqrt{25}

r=5 units.

We substitute into the formula;

(x-h)^2+(y-k)^2=r^2

(x-1)^2+(y-1)^2=5^2

(x-1)^2+(y-1)^2=25

Expand if you wish;

x^2-2x+1+y^2-2y+1=25

x^2+y^2-2x-2y+2-25=0

x^2+y^2-2x-2y-23=0

Please solve #13-14
Serga [27]

Answer:

XZ = 44

KQ = 24

Step-by-step explanation:

XH is half of XZ, and XH is 22x so two times 22x will give you XZ.

XH times two equation - 2(22x)

XZ equation - 43x + 1

Set them equal

2(22x) = 43x + 1

44x = 43x + 1

x = 1

Put x in equation XZ

43(1) + 1 = 44
