URGENT URGENT URGENT Find the value of x.

Mathematics
1 answer:
Alja [10]3 years ago
4 0

Answer:

x = 5.

Step-by-step explanation:

x is the radius of the circle.

The line of length 4 bisects the chord of length 6 into 2 line segments of length 3.

If we draw a line from the centre to where the chord of length 6 meets the circle we have another radius.

This is also the hypotenuse (h) of a right triangle, so we have a right triangle whose legs are 3 and 4, then:

h^2 = 4^2 + 3^2 = 25

h = 5

x = 5 (as x and h are both radii).

Find the circumference of this figure. Show your calculations.
solong [7]

Answer:

Circumference of circle= 37.68 units

Circumference of sector= 6.28 units

Step-by-step explanation:

The given figure is a circle with given radius OB= 6 units.

The circumference of a circle is the total length of its boundary.

For the complete circle its circumference can be calculated by;

           Circumference= 2\pi r

                                 =2*3.14*6\\=37.68 units

For the circumference of the Sector with 60° in the figure, the circumference can be calculate by:

                              =\frac{60}{360}* 2*\pi*6\\\\=\frac{1}{6}*12*3.14\\\\ =2*3.14\\\\=6.28 units

So, the circumference of the full circle is 37.68 units and the circumference of the sector is 6.28 units.

I'm confused how to solve this, can someone help??
frutty [35]
Add one on both sides of the equation. You would end up with -6=x/3. You would then cross multiply, so -6 times 3 and 1 (the denominator for -6) times x and you would get -18=x
