A cylindrical tube 14.0 cm high and 2.5 cm in diameter is used to collect blood samples. how many cubic decimeters (dm3) of blood can it hold (v of a cylinder = r2h) ?

A decimeter is one tenth of meter.

The formula to measure the volume of cylinder is V = h (r^2), where v = volume, r = radius, and h = height.

First, we plug those numbers into the formula. Remember that radius is one half of the diameter.

V = 14 (2.5/2) ^2

Simplify the problem.

V = 21.875

Now, let's convert this answer from centimeters to decimeters.

Since a decimeter is one tenth of a meter, we can divide the answer by ten.

= 21.875/10

Therefore, your answer is 2.1875dm3
