399.6 square meters
7•8/2=28
28•3=84
8•6.9/2=27.6
(12•8)•3=288
84+27.6+288=399.6
Answer:
The chord is bisected.
Step-by-step explanation:
see the attached figure to better understand the problem
In the circle of the figure
The diameter is the segment DE
The chord is the segment AB
PA=PB=r ----> radius of the circle
Triangles PAC and PBC are congruent right triangles by SSS
Because
PA=PB
PC is a common side
AC=BC ----> Applying Pythagoras Theorem
therefore
The chord AB is bisected

Answer:
13
Step-by-step explanation:
We're trying to find the distance between points X and Y. Or the distance of X-Z plus Z-Y.
Lets find the distance of X-Z
6-2=4
Now lets find the distance of Z-Y
15-6=9
Now we add the distances
4+9=13
