A lab technician made a 14 cm diameter hole through the middle of a cylinder that has a diameter of 20 cm and a height of 18 cm. What is the approximate volume of the finished cylinder, to the nearest tenth of a centimeter?

Step-by-step explanation:

we know that

The approximate volume of the finished cylinder, is equal to subtract the volume of the hole from the volume of the original cylinder

so

where

r_1 is the radius of the original cylinder

r_2 is the radius of the hole

we have

---> the radius is half the diameter

---> the radius is half the diameter

substitute the given values in the formula

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.

step-by-step explanation:

there is no grid
