Find x segments of circles

Mathematics
1 answer:
DerKrebs [107]3 years ago
7 0

Answer:

x = -9

x = 2

Step-by-step explanation:

We can say that:

x (x + 7) = 6*3

x² + 7x = 18

x² + 7x - 18 = 0

Now solving by quadratic formula we get;

x = 2, and -9

if we substitute in -9 for x, let's see what happens:

(-9) (-9 + 7) = 6*3

(-9) (-2) = 6*3

18 = 18

therefore x = -9 works! Let's see what happens if we substitute x in for 2;

(2) (2 + 7) = 6*3

(2) (9) = 6*3

18 = 18

Therefore x = 2 works as well!

<u>The final answer would be;</u>

<u>x = -9</u>

<u>x = 2</u>

Hope this helps!

Find the area of the shaded regions below. Give your answer as a completely simplified exact value in terms of π (no approximati
pochemuha

!

Answer:   8 (Pi - sqrt(3))

Discussion:

The area of the shaded region is that of the semicircle minus the area of the triangle..

Area of semicircle = 1/2 * Pi * R^2        

    Where R^2 is the square of the radius of the circle. In our case, R ( = OC)

     = 4 so the semicircle area is

    (1/2) * Pi * (4^2) = (1/2) * Pi * 16 = 8 Pi

Area of triangle.

   First of all, angle ACB is a right angle ( i.e. 90 degrees).

     * This is the Theorem of Thales from elementary Plane Geometry. *

  so by Pythagoras

    AC^2 + BC^2 = AB^2

 But CB = 4 (given) and AB = 4*2 = 8 ( the diameter is twice the radius).

 Substituting these in Pythagoras gives

    AC^2 + 4^2 = 8^2 or

    AC^2 = 8^2 - 4^2- = 64 - 16 = 48

    Hence AC = sqrt(48) = sqrt (16*3) = 4 * sqrt(3)

We are almost done! The area of the triangle is given by

   (1/2) b * h = (1/2)  BC * AC = (1/2) 4 * (4 * sqrt(3)) =  8 sqrt(3)

We conclude the area area of the shaded part is

  8 PI - 8 sqrt(3)   = 8 (Pi - sqrt(3))

Note that sqrt(3) is approx  1.7 so (PI - sqrt(3)) is a positive number, as it better well be!
