Question

A cylindrical tube 13.5 cm high and 4.5 cm in diameter is used to collect blood samples. How many cubic decimeters (dm3) of blood can it hold (V of a cylinder = 72h)? 495.0E-9 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. dm X

Answer 1

The cylindrical tube can hold 0.215 cubic decimeters of blood.

Step-by-step explanation:

Diameter of the cylindrical tube = d = 4.5 cm

r = d/2 ,r = 2.25 cm

Height of the cylindrical tube = h = 13.5 cm

Volume of the cylinder = V =
`\pi r^2h`

`V=3.14* (2.25 cm)^2* 13.5 cm`

`V=214.6 cm^3=0.2146 dm^3\approx 0.215 dm^3`

`1 cm^3=0.001 dm^3`

The cylindrical tube can hold 0.215 cubic decimeters of blood.
