Enrique bought a packing tube to ship a poster to his cousin. If the packing tube had a volume of 1761 cubic centimeters and
an altitude of 11 centimeters, what was the radius of the packing tube?

a.) 16 cm
b.) 12 cm
c.) 7 cm
d.) 4cm

Sagot :

Answer:

r = 7 cm

Step-by-step explanation:

Given that,

Volume of the packing tube, V = 1761 cm²

The altitude of the tube, h = 11 cm

We need to find the radius of the packing tube. The volume of the the cylindrical shaped object is given by :

[tex]V=\pi r^2 h\\\\r^2=\dfrac{V}{\pi h}\\\\r^2=\dfrac{1761}{\pi \times 11}\\\\r=7.13\ cm[/tex]

or

r = 7 cm

So, the radius of the packing tube is 7 cm.
