Question

PLEEEAAAASE HELLP!!!Tina is making a cylindrical sandbox that has a radius of 2 feet. She bought 18.84 cubic feet of sand for the sandbox. Which height does she need to make the sandbox to fit all the sand?0.5 ft, 0.75 ft, 1 ft, 1.5 ft.

Answer 1

Explanation:

The answer is 1.5 ft i just took the test

Answer 2

The correct option is 4.

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)* (2)^2* h`
`[\because \pi=3.14]`

`18.84=(3.14)* 4* h`

`18.84=12.56* h`

`(18.84)/(12.56)=h`

`1.5=h`

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