Enrique bought a packing tube to ship a poster to his cousin. If the packing tube had a volume of 240 cm3 and an altitude of 15 cm, what was the radius of the packing tube?

Answer: the radius of the packing tube is 2.26 cm

Step-by-step 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
