Look to the right of the number in the thousands
place. It's a 6, so round up.
8,636 is rounded to 9,000 because the highest place
value of that number is in the thousands place.</span></span></span>
The area of a circle is the size of the 2-dimensional space inside the circle's
closed curved boundary.
The area can be calculated in terms of known linear measurements of the circle:
-- Area = (π) x (radius)²
-- Area = (π/4) x (diameter)²
-- Area = (1/2) x (circumference) x (radius)
-- Area = (1/4) x (circumference) x (diameter)
Any of these formulas will give you the area. The one you decide to use
just depends on what you already know about the circle.
Answer: 
Step-by-step explanation:
Given the angle of 55 degrees, you know that the adjacent side is "x" and the length of the hypotenuse is 20.
Therefore, you need to remember the following identity:

Then, knowing that:

You need to substitute these values into
:

Now, you can solve for "x":

Rounded to the nearest hundreth:
