<u>Column Vector</u>
Vectors are matrices having only one column or one row. A vector having only one column is called a column vector, and a vector having only one row is called a row vector.
It's required to find the vector AB as a column vector, and we are given the coordinates of A=(6,4) and B=(2,7).
The vector directed from A to B is found by subtracting its corresponding coordinates:
Now we express the vector as a one-column matrix as follows:
Answer:
Divide the figure above into a cylinder and a dome
+) the volume of the dome is
the surface area is
+) the volume of the cylinder is
the surface area is
so the volume of this figure is
the surface area of this figure is
