Answer: the radius of the packing tube is 2.26 cm
Explanation:
The packaging tube is cylindrical. We would apply the formula for determining the volume of a cylinder which is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
From the information given,
Volume = 240 cm³
Height = 15 cm
Therefore,
240 = 3.14 × r² × 15
240 = 47.1r²
Dividing the left hand side and the right hand side of the equation by 47.1, it becomes
r² = 240/47.1 = 5.0955
Taking square root of the left hand side and the right hand side of the equation, it becomes
r = 2.26 cm
