Hello,

x^2+y^2-4x+22y+61=0\\\\
(x^2-4x+4) +(y^2+22y+121)-121-4+61=0\\\\
(x-2)^2+(y+11)^2=64




Center is (2,-11) and radius is 8

Answer:

( 41° * π * radius) / 180

Step-by-step explanation:

The arc measure of major arc ABC on circle P is

( 41° * π * radius) / 180 degrees.

For instance if P = 5 then see the picture, the Arc Length = 3.58

James wants to construct a regular hexagon inscribe in a circle with center O and diameter PQ
Brums [2.3K]

Answer:

B. Place the compass at P and draw an arc of length OP across the circle.

Below is the diagram for help.

Step-by-step explanation:

We are given with an already constructed circle of diameter PQ and OP as radius.

To draw a regular hexagon(six-sided), we need to make first cut on the circle of an arc equal to radius of the circle taking any point of the diameter as center

So here, We will consider P as a center and take an arc of length OP and make a cut on the circle.

This would be the first step and James need to repeat the same steps by considering the newly formed cut as center each time.

35 POINTS PLEASE HELP
Lunna [17]

Answer:

The percentage error of measurement is 5.63 %

Step-by-step explanation:

Given as  :

The measure length of the fence = 150 feet

The actual length of the fence = 142 feet

Let the percentage error in measurement = x

So, x = \dfrac{\textrm measured value - \textrm actual value}{\textrm actual value} ×100

Or, x =  \dfrac{\textrm 150 - 142}{142} ×100

or, x = \dfrac{\textrm 8}{142} ×100

or, x = 5.63 %

Hence The percentage error of measurement is 5.63 %  Answer

Ivan

Answer:

The angle at B is the same as the angle at E so equate them to each other to find x

2x+4=40°

2x=40-4

2x=36

x=36/2=18

Step-by-step explanation:

Hope this is helpful! stay safe and God Bless:)))
