PLEASE HELP ASAP A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 5 inches. The height of the cone is 15 inches. Use π = 3.14. What is the relationship between the volume of this cylinder and this cone? Explain your answer by determining the volume of each and comparing them. Show all your work.

251.327 in^2

Step-by-step explanation:

I looked up the equations and plugged in the numbers. The equation for a cylinder is pi × radius squared × height. The equation for the cone was pi × radius squared × the height divided by 3.

I plugged in the numbers and got these equations

Cylinder:

Cone:

As you can see, if you simplify what's in the parentheses, 15÷3=5. The two equations are exactly the same. So are the volumes, so the cone and the cylinder have the exact same volume.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
