Answer: 0.539 cubic decimeters of blood can be hold by the cylinder.

Step-by-step explanation:

Volume of cylinder= volume of blood it can hold = $\pir^2h$

Given :

Height of cylinder (h) = 9.5 cm

Diameter of cylinder (d) = 0.85 cm

Thus radius of cylinder (r) = $\frac{\text {Diameter of cylinder}}{2}=\frac{0.85cm}{2}=0.425cm$

Putting the values we get:

Volume of cylinder= volume of blood it can hold = $3.14\times (0.425cm)^2\times 9.5cm=5.39cm^3=0.539dm^3$ [tex] (1cm=0.1dm)

Thus 0.539 cubic decimeters of blood can be hold by the cylinder.
