A cylindrical cardboard tube with a diameter of 8 centimeters and a height of 20 centimeters is used to package a gift. What is the approximate volume of the tube? Round to the nearest whole cubic centimeter.

1,005 cm3

1,340 cm3

3,351 cm3

4,021 cm3

The volume of a cylinder can be calculated by multiplying the area of its base times the height. It is calculated as follows:

V = πr²h

V = π (8/2) ² (20)

V = 1005.31 cm³

Therefore, the correct answer is option 1. Hope this answers the question. Have a nice day.
