The formula is $\pi r^2h$ r= radius
h= height
you square the radius and then multiply by the $\pi$ and then the height

1). Recall the formula for the volume of a cylinder:

Volume = (pi) x (radius of the round end)² x (length or height) .

2). Gather together the number you'll use for pi, the radius of the
cylinder's round end, and its length or height. Make sure that the
radius of the round end and the length or height are in the same units.
If they're not, then convert something so that they are.

3). Write each number into its place in the formula.

4). Perform the indicated operations. The final number is the
volume of your cylinder.

Can someone explain how to solve and find x on the triangle

Romashka [77]

Step-by-step explanation:

sum of all the angles in a triangle is equal to 180°

82 + 70 + (2x + 4) = 180

152 + 2x + 4 = 180

156 + 2x = 180

2x = 180 - 156

2x = 24

x = 12

Round to the nearest tenth

<em>Note: I am assuming we have to determine the value of the side 'x'.</em>

Answer:

The value of x = 8.1 units

Step-by-step explanation:

<em>Note: I am assuming we have to determine the value of the side 'x'.</em>

Given

Angle Ф = 32°

To determine:

x = ?

Using the trigonometric ratio

tan Ф = opposite / adjacent

here

Ф = 32°

opposite to angle 32° = x

adjacent to angle 32° = 13

Therefore,

substituting adjacent = 13, Ф = 32°, opposite = x in the equation

tan Ф = opposite / adjacent

$\tan \left(32^{\circ \:}\right)=\frac{x}{13}$

$\:x\:=\:13\:\times tan\:32^{\circ }\:$

x = 8.1 units tan 32° = 0.62

Therefore, the value of x = 8.1 units

Find the solutions of the following equations by extracting square roots 9x2-16=0 (z-2)2-36=0

natta225 [31]

The solutions of the equation $9x$ ² - 16 = 0is 4/3 and -4/3 and that of the equation $(z - 2)^{2} - 36 = 0$ is 8 and -4.

Solving the both quadratic equations by extracting square roots:

$9x^{2} - 16 = 0$

⇒ $9x^{2} = 16$

∴ On taking square-root of both sides, we get

$\sqrt{9x^{2} }$ = $\sqrt{16}$

⇒ $3x =$ $+4$ and $3x = -4$

⇒ $x$ = 4/3 and $x$ = -4/3

For the equation, $(z - 2)^{2} - 36 = 0$ , the solution is:

$(z - 2)^{2} - 36 = 0$

⇒ $(z - 2)^{2} = 36$

∴ On taking square-root of both sides, we get

$\sqrt{(z - 2)^{2} } = \sqrt{36}$

⇒ (z - 2) = 6 and (z - 2) = -6

⇒ z = 6 +2 and z = -6 + 2

⇒ z = 8 and z = -4

The solution of the equation $9x^{2} - 16 = 0$ is 4/3 and -4/3.

The solution of the equation $(z - 2)^{2} - 36 = 0$ is 8 and -4.
