Answer:

d. V = π(x^3 + 90x^2 + 2,400x + 20,000)

Step-by-step explanation:

volume of cylinder = πr^2h

We have r = x + 20; h = x + 50

V = π(x + 20)^2(x + 50)

V = π(x^2 + 40x + 400)(x + 50)

V = π(x^3 + 50x^2 + 40x^2 + 2000x + 400x + 20,000)

V = π(x^3 + 90x^2 + 2,400x + 20,000)

Answer:

<em>Probability ≈ 0.3571</em>

Step-by-step explanation:

Consider the steps below;

$Total Number of Outcomes - 9C4,\\9 ! / 4 ! * ( 9 - 4 ),\\9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 / 4 * 3 * 2 * 1 * 5 * 4 * 3 * 2 * 1,\\\\Total Outcomes = 126,\\\\Number of Outcomes - 3C2 * ( 6C2 ),\\3C2 = 3,\\6C2 = 15,\\\\Number of Outcomes = 3 * 15 = 45,\\\\Probability; 45 / 126 = ( About ) 0.3571$

<em>Solution; Probability ≈ 0.3571</em>

Find the volume of a pyramid with a square base, where the area of the base is

never [62]

Answer:

$V=60.28\ cm^3$

Step-by-step explanation:

Given that,

The area of the base = 13.2 cm²

The height of the pyramid = 13.7 cm

We need to find the volume of this pyramid. The formula can be given by :

$V=\dfrac{1}{3}Bh$

Put all the values,

$V=\dfrac{1}{3}\times 13.2\times 13.7\\\\V=60.28\ cm^3$

So, the volume of the pyramid is equal to $60.28\ cm^3$ .

Explain the connection between ∠2 and ∠B. A triangle has angle measures 50 degrees, 65 degrees, and B. 2 lines extend from a hor

Furkat [3]

Since the two angles are equal, hence the angles B and angle 2 are congruent.

<h3>Congruent triangles</h3>

Congruent triangles are triangles that are similar to each other

Since the sum of the interior angles of a triangle is 180°, then

m∠B + 50° + 65° = 180°

Determine the value of <B

m∠B = 180° - (50° + 65°)

m∠B = 180° - 115°

m∠B= 65°.

Similarly, the sum of angle on a straight line is 180 degrees

m∠2 + 50° + 65° = 180°

m∠2 = 180° - (50° + 65°)

m∠2 = 180° - 115°

m∠2= 65°

As we can see that the two angles are equal, hence the angles B and angle 2 are congruent.
