Step-by-step explanation:

The answer is 1.5 ft i just took the test

Answer:

The correct option is 4.

Step-by-step explanation:

The volume of a cylinder is

[tex]V=\pi r^2h[/tex]

where, r is radius of the base and h is height of the cylinder.

It is given that the radius of the cylindrical sandbox is 2 ft and the volume of cylindrical sandbox is 18.84.

[tex]18.84=(3.14)\times (2)^2\times h[/tex]        [tex][\because \pi=3.14][/tex]

[tex]18.84=(3.14)\times 4\times h[/tex]

[tex]18.84=12.56\times h[/tex]

[tex]\frac{18.84}{12.56}=h[/tex]

[tex]1.5=h[/tex]

The height of the sandbox is 1.5 ft. Therefore the correct option is 4.
