a solid consists of cylinder surmounted by a right circular cone. The height of the cone is 2h. If the volume of the solid is 3

Mademuasel [1]

Answer:

height of cylinder = 4/3 h

Step-by-step explanation:

The solid has a cylinder surmounted with a cone .Therefore, the volume of the solid is the sum of the cone and the cylinder.

volume of the solid = volume of cylinder + volume of cone

volume of the solid = πr²h + 1/3πr²h

let

height of the cylinder = H

recall

the height of the cone = 2h

volume of the solid = πr²h + 1/3πr²h

3(1/3πr²2h) = πr²H + 1/3πr²2h

2πr²h = πr²H + 2/3 πr²h

πr²(2h) = πr²(H + 2/3 h)

divide both sides by πr²

2h = H + 2/3 h

2h - 2/3h = H

H = 6h - 2h/3

H = 4/3 h

height of cylinder = 4/3 h

How would you graph the solution set of x - 6 < - 3?

melomori [17]

Move all terms not containing x to the right side of the inequality. You should get x<3

This is what your line should look like. The circle will be open because the is not line under the less than sign. And it will be going toward the left because it is less than greater than is graphed to the right.

Here is the question !

Delvig [45]

Answer:

Step-by-step explanation:

Co-ordinates of F, G and H are:

F (-4, 5)

G (1, 10)

H (-9, 10)

You can find the lengths of sides by using the distance formula:

length(FG) = $\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}$ = $\sqrt{(1-(-4))^{2} + (10-5)^{2}} = 5\sqrt{2}$ units

Similarly,

length(GH) = 10 units

length(HF) = $5\sqrt{2}$ units

Hence, perimeter will be:

P = length(FG) + length(GH) + length(HF) = $10(\sqrt{2} + 1)$ units
