Explain how the volume of a right cone relates to the volume of a cylinder with the same base
and height. Use diagrams and volume formulas to explain the relationship.

Answers

Answer 1

Answer:

its 1/3 of the volume of a cyinder with the same base

Step-by-step explanation:

a pyramid has the same policy with prisms of the same base

Answer 2

Volume is a three-dimensional scalar quantity. If the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.

What is volume?

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Assume a cone and a cylinder such that the radius of the base of both the figures is r units, while the height of the cone and cylinder both is h units.

The volume of the cone with radius r units and height h units now can be written as,

Volume of the cone = (1/3) × π × r² × h units³

The volume of the cylinder with a radius of r units and the height of h units now can be written as,

Volume of the Cylinder = π × r² × h units³

Taking the ratio of the volume of the cone and the volume of the cylinder,

Volume of the cone/Volume of the cylinder = (1/3)πr²h units³ / πr²h units³

Volume of the cone/Volume of the cylinder = 1/3

Volume of the cylinder = 3 × Volume of the cone

Hence, if the radius and the height of a cone and a cylinder are the same, then the volume of the cylinder is thrice the volume of the cone.

Answers

Answer:

x = 1 and y = 7

Step-by-step explanation:

First, you substitute the y into the first equation

-5x+2(7x)=9

-5x+14x=9

9x=9

x=1

Then put the x into the equation to find y

First subtract the 9:

65 - 9 = 56

Then divide by 2:

56 ÷ 2 = 28

28 is one of your answers. If we want to find the other one, then add back 9

work out the equation of a line which has a gradient of -2 and passes through the point (1 ,7)​

Answers

Answer:

Y=-2x+9

Step-by-step explanation:

The first thing is to know the formula which is Y÷x

Then... The line (1,7)use the coordinates Y and X so it will be as follows... Label 1 and 7 as x, y

So it will be Y-7÷X-1 = the gradient which is - 2

So multiply both sides by X-1

So it will be Y-7=2x+2 again be careful because a negative number multiplied by another negative will give you a positive sign

Remember Y-7....... Take 7 to the other side so it will be a positive...... Then work out the integers

Which translation takes y = | x + 2 | - 1 to y = | x | + 2 ?

Select one:
a. 2 units left, 3 units down
b. 2 units left, 3 units up
c. 2 units right, 3 units up
d. 2 units right, 3 units down

(Solve by graphing and determining the translation. Thanks in advance!)

Answers

Answer:

C

Step-by-step explanation:

y = | x + 2 | − 1 has a vertex at (-2, -1).

y = | x | + 2 has a vertex at (0, 2).

So the graph is translated 2 units right and 3 units up.

Find the measure of each numbered angle

Answers

measure of angle 1 is 56
measure of angle 2 is 56
measure of angle 3 is 74

All triangle’s angles add up to 180

The measure of each numbered angles are ∠1 =  56°, ∠2 = 56° and ∠3 = 74°.

What is Angle?

An angle for any figure is formed by two rays which joins at a common point called vertex or node.

Usually angles are measured in degrees or radians.

Consider triangle PMQ

The sum of the interior angles of a triangle is 180°.

∠MPQ + ∠QMP + ∠PQM = 180°

58° + 66° + ∠1 = 180°

∠1 =  180° - (58° + 66°)

∠1 =  180° - 124°

∠1 =  56°

Now, ∠1 and ∠2 are vertically opposite angles. Hence they are equal.

∠2 = 56°.

Again, for triangle NQO

∠2 + ∠3 + 50° = 180°

56° + ∠3 + 50° = 180°

∠3 = 180° - (50° + 56°)

∠3 = 180° - 106°

∠3 = 74°

Hence ∠1, ∠2 and ∠3 are 56°, 56° and 74° respectively.

An equilateral triangle with side lengths of 7 units is translated 3 units to the right. What is the length of one side of the triangle after the translation, in units? 3 units

Answers

Answer:

[tex]Sides= 7\ units[/tex]

Step-by-step explanation:

Given

[tex]Sides= 7\ units[/tex]

[tex]Translation = 3\ units[/tex] (to the right)

Required

Determine the length of one side after translation

It should be noted that when a shape, line, object is being translated by shifting its position, only the position of the shape, line or object changes not its length

This implies that, the length of the sides of the equilateral triangle remain unchanged.

Hence:

[tex]Sides= 7\ units[/tex]

The figures are similar. Find the missing length.Round to the nearest thousandth ​

Answers

Answer:

The missing x = 0.675 m

Step-by-step explanation:

In similar triangles, the corresponding sides are proportion (means their ratios are equal)

In the given figure

∵ The two triangles are similar

∴ Their corresponding sides are proportion

∵ The sides of lengths 1.8 m and x are corresponding sides

∵ The sides of lengths 8.0 m and 3.0 are corresponding sides

∴ [tex]\frac{1.8}{x}[/tex] = [tex]\frac{8.0}{3.0}[/tex]

→ By using cross multiplication

x × 8.0 = 1.8 × 3.0

∴ 8x = 5.4

→ Divide both sides by 8

∵ [tex]\frac{8x}{8}[/tex] = [tex]\frac{5.4}{8}[/tex]

x = 0.675

→ No rounding because there is no digit after the thousandth digit

x = 0.675 m
