Answer: 230cm²
Step-by-step explanation:
>We can do this by splitting the figure into 2 trapeziums.
>Additionally, you can see that both trapeziums bear the same lengths a and b. Hence, we can use this formula:
.
>Thus,
Area = 
Slope = -1/2
y-intercept = 6

Answer:
The center of the circle is
.
Step-by-step explanation:
The center of the circle is the midpoint of the segment between the endpoints. We can determine the location of the center by this vectorial expression:
(1)
Where:
- Center.
,
- Location of the endpoints.
If we know that
and
, then the location of the center of the circle is:



The center of the circle is
.
