Answer:

V ≈ 254.5 in³

Step-by-step explanation:

The volume (V) of the cylindrical tube is calculated as

V = πr²h ( r is the radius and h the height ) , then

V = π × 3² × 9 = π × 9 × 9 = 81π ≈ 254.5 in³ ( to 1 dec. place )

How do I find X for this problem? I’m stuck

Bas_tet [7]

Corresponding sides of the two triangles occur in a ratio with one another. In particular, you have the relationship

$\dfrac6{6+x}=\dfrac{10}{15}=\dfrac y{y+4}$

We only need the first two parts to solve for $x$ :

$\dfrac6{6+x}=\dfrac{10}{15}\implies6\cdot15=10(6+x)\implies90=60+10x\implies30=10x$

$\implies\boxed{x=3}$

Answer:

Pattern seen is arithmetic progression. The both equations are same.

Step-by-step explanation:

a.The given pattern is 8,12,16,20,24....We can see that the difference between any two consecutive terms is 4.Therefore this is an AP(arithmetic progression).

b.Percy's equation , $N = 8 + 4(s-1)\\$

⇒ $N = 8 + 4s - 4$

⇒ $N = 4s + 4$

⇒ $N = 4(s+1)$

which is the same as Stella's equation . So , we can see that both equations are the same.
