Pleeese ! 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.

Step-by-step explanation:

The answer is 1.5 ft i just took the test

The correct option is 4.

Step-by-step explanation:

The volume of a cylinder is

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.

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

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
