C. 271.44

Step-by-step explanation:

We need to first find the volume of the pipe, then find the volume of the hole and then subtract the volume of the hole from the volume of the pipe.

The diameter of the pipe is 8.4 mm. This means its radius is:

8.4/2 = 4.2 mm

The height of the pipe is 10 mm

The volume of a cylinder is given as:

where r = radius

h - height

Therefore, the volume of the cylinder  without the hole is:

The diameter of the hole is 6 mm. Its radius is:

6/2 = 3 mm

The volume of the hole is:

The volume is:

554.18 - 282.74 = 271.44

B. 271.3

Step-by-step explanation:

Volume of the outer cylinder minus the volume of the inner cylinder returns the volume of the metal outer ring that surrounds the hole.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
