Answer:
Step-by-step explanation:
The equation for a circle is 
, where 
is the vertex of the circle and 
is the radius. Immediately, since the center of the circle is given, we know what 
and 
are. is 230 and is 220.
The only thing we need to find is the radius, which will just be the distance from the center (230,220) to a point on the circumference (170,170). The distance between them can be calculated using the <u>distance formula</u>, which is really just the <u>Pythagorean Theorem</u> rearranged. The formula states that 
, where 
is the change in the x-coordinates of the two points and 
is the change in the y-coordinates of the two points. Plug-in for 60 and for 50 to get 
. Solve for 
, arriving at 
. Therefore, the radius of the circle is .
Finally, we have all of the components to create the equation of the circle. Plug-in 230 for , 220 for , and for .
The equation of the circle will be .

Answer:
When to lines intersect they create four angles. Each angle is opposite to another and form a pair of what are called opposite angles. Angles a and c are opposite angles. Angles b and d are opposite angles. Opposite angles are equal.
Well, if 0.4% was defected, then 99.6% of the parts are good, because 100-0.4 is 99.6. Multiply 99.6% with 54650, and you get 54431.4. You should round down, because you can't have parts of parts. So, 54431 parts were good.
