Answer:
15.1
Step-by-step explanation:
We know that the area of the circle is 
, but we are looking for the portion of the circle, this means we multiply it by the portion of the circle that is shaded.
Area of shaded region = 
where r = 4 and x = 108, the 360 comes from the fact that the total degrees around the circle is 360, so dividing the total amount of degrees by the angle will give us the portion we are looking for.
Area of shaded region = 
= 15.1
Another way to think about it is that the area of the total circle is , multiplying it by a fraction, a number less than 1, would give us a smaller value.
Hope this helps.
I beleive it would be 5,2 but I'm not too sure
Answer:
A=a^2
Step-by-step explanation:
Geometry:
In geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles. It can also be defined as a rectangle in which two adjacent sides have equal length. A square with vertices ABCD would be denoted \square ABCD.
Square Roots:
In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x. For example, 4 and −4 are square roots of 16, because 4² = ² = 16.
