How much of the circle is shaded? Write your answer as a fraction in simplest form.
1 answer:
Answer:
of the circle is shaded.
Step-by-step explanation:
Circle Consists of 3 parts.
First part is the shaded part.
Now Given:
Portion of Second part =
Also Given:
Portion of Third part =
We need to find the portion of shaded part.
Solution:
We know that 1 whole circle is divided in 3 parts.
So Portion of shaded part will be equal to 1 circle minus Portion of Second part minus Portion of third part.
framing in equation form we get;
Portion of shaded part =
Now taking LCM for making the denominator common we get;
Portion of shaded part =
Hence We can say that of the circle is shaded.

First, let 
be a point in our parabola. Since we know that the focus of our parabola is the point (0,8), we are going to use the distance formula to find the distance between the two points:
Next, we are going to find the distance between the directrix and the point in our parabola. Remember that the distance between a point (x,y) of a parabola and its directrix,
, is: 
. Since our directrix is y=-8, the distance to our point will be:
Now, we are going to equate those two distances, and square them to get rid of the square root and the absolute value:
Finally, we can expand and solve for
:
We can conclude that t<span>he standard form of the equation of the parabola with a focus at (0, 8) and a directrix at y = -8 is </span>
