Question

A right circular cylinder has a height of 22 1/4 ft and a diameter 2 2/5 times its height. What is the volume of the cylinder? Enter your answer in the box. Use 3.14 for pi and round only your final answer to the nearest hundredth. _ ft³

Answer 1

Since all the fractions are terminating decimals, convert all fractions to decimals for easy working.

-------------------------------------
Height :
-------------------------------------
Height = 22.25 ft

--------------------------------------
Diameter :
-------------------------------------
Diameter = 2.4 x 22.25
Diameter = 53.4 ft

-------------------------------------
Radius :
-------------------------------------
Radius = Diameter ÷ 2
Radius = 53.4 ÷ 2
Radius = 26.7 ft

-------------------------------------
Volume :
-------------------------------------
Volume of the cylinder = πr²h
Volume of the cylinder = 3.14 x 26.7² x 22.25
Volume of the cylinder = 49806.06 ft² (nearest hundredth)

--------------------------------------------------------------------------
Answer : Volume = 49806.06 ft²
--------------------------------------------------------------------------
