Prism M and pyramid N have the same base area and the same height. Cylinder P and prism Q have the same height and the same base

Answer:

Answer Cone Z and Cylinder Y.

Step-by-step explanation:

The relationship between the volume of the cone and the volume of the cylinder with the same height and same base is the volume of the cone is 1/3 of the volume of the cylinder.

The formula for the volume of the cone is :

V = 1/3π $r^{2}$ h

The formula for the volume of the cylinder is :

V = π $r^{2}$ h

Let be the height of the cylinder Y. Therefore the height of the cone Z is 3h, when we put it into the formula we get :

V = 1/3π $r^{2}$ (3h) = π $r^{2}$ h

Therefore Cone Z and Cylinder Y have same volume.

What if we say that x's value is 2. Do 2x and x to the second power have the same value?

Basile [38]

Yes. Substitute 2 for x.

We have

The radius of a circle is 6.5 inches. Find the circumference of the circle. Use pi as 3.14. Explain your steps.

Viefleur [7K]

Circumference= 2piR
1) Fist do 2 times pie. 2x3.14= 6.28
2) With the remaining answer times it by the radius. 6.28x6.5= 37.994inches
