The sum of 3 consecutive number multiples of 6 is 162 find thesse numbers

MAXImum [283]

let the numbers are x , x+1 ,x+2

∴ 6 [ x + (x+1) +(x+2) ] = 162

∴ x + (x+1) + (x+2) = 162/6 = 27

∴3x + 3 = 27

∴ 3x = 27 - 3 = 24

∴ x = 24/3 = 8

<u>So, the numbers are 8 , 9 , 10</u>

A cylinder has 18 inch diameter and is 15 inches tall it is filled to the top with water a 6 inch diameter ball is in place with

k0ka [10]

Answer: $1,179\pi\ in^3$

Step-by-step explanation:

The volume of a cylinder can be calculated with the following formula:

$V=\pi r^2h$

Where "r" is the radius and "h" is the height.

The volume of a sphere can be found with this formula:

$V=\frac{4}{3}\pi r^3$

Where "r" is the radius.

Then, volume of the empty cylinder is:

$V_c=\pi (\frac{18\ in}{2})^2(15\ in)\\\\V_c=1,215\pi \ in^3$

And the volume of the ball is:

$V_b=\frac{4}{3}\pi (\frac{6\ in}{2})^3\\\\V_b=36\pi \ in^3$

Finally, you need to subtract them in order to calculate how much water is in the cylinder:

$1,215\pi \ in^3-36\pi \ in^3=1,179\pi\ in^3$

PLS SOLVE ASAP!!!!<br> Solve for angle 1.

dangina [55]

∠1 + ∠2 = 180°
⇒ 2x + 10x = 180°
⇒ 12x = 180°
⇒ x = 180°/12 = 15°

∠1 = 2x = 2×15° = 30°
