Question

Cylindrical tube 9.5cm high and 0.85 cm in diameter is used to collect blood samples. How many cubic decimete?

Answer 1

A decimetre is 10 centmetres.  So first convert your dimensions into decimetres.

height = 9.5 cm = 0.95 dm

diameter = 0.85 cm = 0.085 dm

Volume of a cylinder = h*pi*r²

volume = 0.95*pi*(0.085/2)²

volume = 0.0054 dm³

Answer 2

cylindrical tube 9.5cm high and 0.85 cm in diameter is used to collect blood samples. How many cubic decimete?

dmizok here it is:

dicemeter = 1000 cm

Given:

Height = 9.5 cm

Diameter = 0.85 cm

Volume = Base Area x Height

Volume = π D²/4 x Height

Volume = π (0.85)²/4 x 9.5

--------------------------------------...

Volume = 5.39 cu cm

or

Volume = 5.39 cu cm x 1dcm/1000cm x 1dcm/1000cm x 1dcm/1000cm

Volume = 0.00000000539 cu dcm

or

Volume = 5.39 x 10^-9 cu dicemeter.
