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.
Answer:
<h2>3.6</h2>Step-by-step explanation:
We're going to use length DC and ML, along with DA and MJ
which is 0.833333333
now for
which is 0.833333333 (again)
as you can see since the shapes <em>ABCD</em> and <em>JKLM</em> are similar, they have a relationship which in this case is 0.833333333
and we can use this <u>0.833333333</u> to help us find the length of <em>KL</em>
knowing that any length for <em>ABCD</em> divided by <em>JKLM</em> is 0.833333333
we can do
since we don't know what <em>KL </em>is, we can switch the spots and enlongate it, to become:
put in the value for <em>CB</em>
<em />
and we get 3.6
The length of x of KL is...
