Answer:

Step-by-step explanation:

As there are 7 numbers 6. 12, 7, 5, 11. 6 and 9.

We rearrange

5, 6. 6, 7, 9, 11, 12.

7 is the 4th number in the data set = middle number of 7

As there are 7 numbers.

A line with a slope of o passes through the points (9, z) and (-7, 5). What is the value of z?

pogonyaev

Answer:

z = 5

Step-by-step explanation:

m = ∆y/∆x = y₂-y₁/x₂-x₁

0 = y₂-y₁/x₂-x₁ = 5 - z / -7 - 9 = 5 - z / -16 →

5 - z / -16 = 0 → 5 - z / -16 × -16 = 0 × -16 → 5 - z = 0 →

5 - z - 5 = 0 - 5 → -z = -5 → z = 5

Plzz look into the question in the attachements

Given : Diameter of the right circular cone ==> 8 cm

It means : The Radius of the right circular cone is 4 cm (as Radius is half of the Diameter)

Given : Volume of the right circular cone ==> 48π cm³

We know that :

$\bigstar \ \ \boxed{\textsf{Volume of a right circular cone is given by : $\pi r^2\dfrac{h}{3}$}}$

where : r is the radius of the circular cross-section.

h is the height of the right circular cone.

Substituting the respective values in the formula, we get :

$\mathsf{\implies \pi \times (4)^2 \times \dfrac{h}{3} = 48\pi}$

$\mathsf{\implies 16 \times \dfrac{h}{3} = 48}$

$\mathsf{\implies \dfrac{h}{3} = 3}$

$\implies \boxed{\mathsf{h= 9 \ cm}}$

<u>Answer</u> : Height of the given right circular cone is 9 cm
