Question

A cylinder is 14cm in diamater and 150mm in length. Calculate the volume of the cylinder in dm^3 and mm^3

Answer 1

convert the 14cm to mm
14cm x 10 mm/1cm
divide the diameter by 2 to get the radio

then calculate the volume of the cylinder in mm^3
V=πr2h

then convert the volume in mm^3 to dm^3 with the conversion factor (1dm/100mm)^3

Answer 2

is one of the answers 2.31dm^3?

Answer 3

yes
