Answer:
Area of the sector is 558.22ft².
Explanation:
A= N/360(πr²)
where;
N=160°
π=3.14
r=20
A= 160/360(3.14(20)²)
A= 160/360(3.14(400))
A= 160/360(1256)
A=558.22ft.
Recall that area is measured in square units. And the unit of the radius is ft. Therefore our final answer becomes 558.22ft².
Also note that a sector is the part of a circle enclosed by two radii of a circle and their intercepted arc. It iseasily noted to be the pie-shaped part of a circle.
The global carbon dioxide levels increase the temperature when higher, and lower the temperature when lower.
Explanation:
The carbon dioxide is the most abundant and most important greenhouse gas. This gas has the property to trap and keep heat, thus instead of the heat going back into space, it is retained in the atmosphere. To put is simple, the more abundant the carbon dioxide is in the atmosphere, the higher the temperatures are, the lower the levels of the carbon dioxide, the lower the temperatures.
In recent times, the global carbon dioxide levels are experiencing an increase. While this is mostly due to the natural processes, the humans have been having bigger and bigger influence because of their activities. With the constant rise of carbon dioxide levels in the atmosphere, the temperatures have been gradually rising, and if the current trends continue it is expected that the global temperatures may rise by several C degrees.
The countries that contribute the most to the carbon dioxide emissions are:

Mercator projection is a type of map projection invented and introduced by Gerardus Mercator in the year 1569. The meridians are equally spaced, parallel vertical lines and the parallels of latitude are parallel horizontal lines spaced farther apart as their distance from the equator increases.
This projection is widely used for navigation charts because any straight line on a Mercator- projection map is a line of constant true bearing that enables a navigator to plot a straight-line course.
It is often described as a cylindrical projection but it must be derived mathematically.
