The correct option is 4.

Step-by-step explanation:

The volume of a cylinder is

$V=\pi r^2h$

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.

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

$18.84=(3.14)\times 4\times h$

$18.84=12.56\times h$

$\frac{18.84}{12.56}=h$

1.5=h

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