The height of the cone is 4 cm (approx).

Step-by-step explanation:

Given,

The radius (r) of the cone = 4.96 cm

Volume (V) = 102 cm³

To find the height (h) of the cone.

Formula

The volume of a cone V = $\frac{1}{3}$ πr²h

Now,

According to the problem,

$\frac{1}{3}$ πr²h = 102

or, $\frac{1}{3}$ × $\frac{22}{7}$ ×(4.96)²h= 102

or, h = $\frac{102X7X3}{4.96^{2}X22 }$

or, h = 3.95 = 4 (approx)

so,

Height = 4 cm (approx)

Answer:

The answer to your question is:

Step-by-step explanation:

1.-

y = 84°

5x - 61 = 84

5x = 84 + 61

5x = 145

x = 29

2.-

m∠1 + m∠6 = 180 they are supplementary angles

∠1 = 180 - 143

∠1 = 37

∠1 = ∠ 3 because are vertical angles.

3.-

m∠2 + m∠5 = 180 they are supplementary angles

∠2 + 79 = 180

∠2 = 180 - 79

∠2 = 101

m∠3 = m∠5 they are alternate angles

What is the domain and range of each function?

liubo4ka [24]

Answer:

1. Domain: (3, 5, 7, 8, 11)

Range: ( 6, 7, 9, 14)

2. Domain: (-3, -1, 2, 5, 7)

Range: (-7, -5, -4, 5, 9)

Step-by-step explanation:

The domain is the set of all x values in the function. The range is the set of all y values in the function. It is written in parenthesis from least to greatest. Do not repeat values even if the function has them more than once.

1. Domain: (3, 5, 7, 8, 11)

Range: ( 6, 7, 9, 14)

2. Domain: (-3, -1, 2, 5, 7)

Range: (-7, -5, -4, 5, 9)
