<h3>
The complete exercise is: " A circle has a radius of 6. An arc in this circle has a central angle of 330 degrees. What is the arc length?"</h3><h3>
</h3>
To solve this exercise you need to use the following formula to find the Arc lenght:

Where "C" is the central angle of the arc (in degrees) and "r" is the radius.
In this case, after analize the information given in the exercise, you can identify that the radius and the central angle in degrees, are:

Therefore, knowing these values, you can substitute them into the formula:

And finally,you must evaluate in order to find the Arc lenght.
You get that this is:

Step-by-step explanation:
(4x-23)2-3=2
(4x-23)(-1)=2
4x-23= -2
4x= -2+23
=21
x=21/4
=5.2
Define natural hazard?
A natural hazard is a natural phenomenon that might have a negative effect on humans and other animals, or the environment. Natural hazard events can be classified into two broad categories: geophysical and biological.
What is the difference between tectonic hazards and weather hazards ?
Tectonic hazards occur when the Earth's crust moves. For example, when the plates move, friction can cause them to become stuck. Tension builds until the plates release, which leads to an earthquake. Climatic hazards occur when a region has certain weather conditions, for example heavy rainfall can lead to flooding.
why do convection currents in the mantle occur?
Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart
