Plz help people I have been struggling

3. 42.41 in^2

4. 21.21 in^3

Step-by-step explanation:

So for #3 it is basicly asking for the surface area and the formula for that is 2πrh+2πr^2.

So r is the radius and h is the height. The radius is 1.5 because at the top it says the diameter is 3 and the radius is half the diameter.

Then the height is 3 inches.

so if you plug the radius and height into r and h you get 42.41 in^2.

For number 4 it is asking for the volume.

The formula for volume is πr^2h.

The r is the radius and the h is the height.

The radius is 1.5 and the height is 3.

If you plug those in you get 21.21 in^3.

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
