Answer:
Zero.
Step-by-step explanation:
The determinant of the coefficient matrix of the system is zero, since every coefficient is equal to zero.
A=pi(r)^2
We have the diameter. To get the radius divide it by 2.
The radius now is equal = 13.
Pi=3.14
Distribute it to the equation... A=3.14(13)^2
The area is equal = 530.66
