Answer:
I'm not exactly sure, but I would say the answer is B.
Step-by-step explanation:
The area of a circle is:
A=πr^2, area=pi times the radius squared...
In this case the radius, r, is equal to 6mm so
A=π(6^2) mm^2
A=36π mm^2
So the area is 36π mm^2, where the units are square millimeters
Answer:
look at the pivots (the leading 1's of the rows)
Step-by-step explanation:
Then, look at the pivots (the leading 1's of the rows). If we have a pivot in every column, then the nullspace of the matrix (and hence the kernel of T) is zero-dimensional. So, T is one-to-one if and only if the REF has pivot in every column.
