Answer:

7 people

Step-by-step explanation:

You would count the number of x's shown above any numbers greater than 8 and because there are 6 x's above 9 and 1 x above 10, there would be 7 in all.

Here we go ~

h = height of cone = 10 cm

r = radius of cone/sphere = ??

Volume of cone = 270 pi cm³

Volume of cone is :

$\qquad \sf \dashrightarrow \:v = 270 \pi$

$\qquad \sf \dashrightarrow \: \dfrac{1}{3} \cancel\pi {r}^{2} h = 270 \cancel\pi$

$\qquad \sf \dashrightarrow \:r {}^{2} \sdot10 = 270 \times 3$

$\qquad \sf \dashrightarrow \: {r}^{2} = 810 \div 10$

$\qquad \sf \dashrightarrow \: { {r}^{2} }^{} = 81$

$\qquad \sf \dashrightarrow \:r = \sqrt{81}$

$\qquad \sf \dashrightarrow \:r = 9 \: \: cm$

Now, let's calculate volume of solid sphere with same radius is ~

$\qquad \sf \dashrightarrow \:vol = \dfrac{4}{3} \pi {r}^{3}$

$\qquad \sf \dashrightarrow \:vol = \dfrac{4} {3} \sdot\pi \sdot {9}^{3}$

$\qquad \sf \dashrightarrow \:vol = \dfrac{4} {3} \sdot\pi \sdot 729$

$\qquad \sf \dashrightarrow \:vol = {4} {} \sdot243 \sdot\pi$

$\qquad \sf \dashrightarrow \:vol = 97 2\pi \: \: {cm}^{3}$

So, volume of the solid sphere in terms of pi is :

972 pi cm³

<u>note</u> : the solid figure attached below the cone is a hemisphere, so if the volume of hemisphere is asked then just dovide the result for sphere by 2. that is :

972pi / 2 = 486 pi cm³

Which polynomial is equal to (2x^2-5x-4)-(4x^2-3x-2) , and how is it equal?

Mademuasel [1]

Answer:

A. -2x^2-2x-2

Step-by-step explanation:

(2x^2-5x-4)-(4x^2-3x-2)

distribute the minus sign

(2x^2-5x-4)-4x^2+3x+2

2x^2-5x-4

-4x^2+3x+2

-------------------------

-2x^2 -2x-2

True or false? The graph represents a function. 5. -5 5 2.5 O A. True O B. False

hichkok12 [17]

Answer:

True

Step-by-step explanation:

In functions, each x value has its own corresponding y value, this meaning that the x value cannot repeat, and if it does it is not considered a function

Looking at the graph, no x value repeat, thus the graph represents a function
