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?

She need a height of 1.5 ft

Step-by-step explanation:

First we have to know that the volume of a cylinder is calculated by multiplying the area of its base by the height.

v = 18.84 ft

h = ?

a = ?

v = a * h

we clear the value of h

v = a * h

h = v/a

h = 18.84/?

as we see we do not know the value of a, but we can calculate it with the following formula

π = 3.141592

r = 2ft

a = π * r²

a = π * (2ft)²

a = 12.57 ft²

now that we calculate the area we can go back to our previous formula and get the height

h = v/a

h = 18.84  ft³/ 12.57 ft²

h = 1.5 ft

this is a very good question

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
