A trash can in the shape of a cylinder has a radius of 26 cm and a height of 39 cm. Which of the following is closest to the vol

My name is Ann [436]

Answer:

The volume of cylindrical trash is 82,782.96 cm³ .

Step-by-step explanation:

Given as :

The shape of the trash is cylinder

The radius of cylinder = r = 26 cm

The height of cylinder = h = 39 cm

Let The volume of cylindrical trash = v cm³

<u>Now, According to question</u>

volume = $\Pi \times radius^{2}\times height$

where $\pi$ = 3.14

So, v = 3.14 × r² × h

Or, v = 3.14 × (26)² × (39)

Or, v = 3.14 × 26,364

∴ v = 82,782.96 cm³

So, volume of cylindrical trash = v = 82,782.96 cm³

Hence, The volume of cylindrical trash is 82,782.96 cm³ . Answer

Nth term of this sequence please 18, 16, 14, 12

Annette [7]

Answer:

$\boxed{\sf -2n+20}$

Step-by-step explanation:

Let’s find the common difference.

The common difference can be found by subtracting a term in the sequence with the previous term.

$\sf d=16-18\\d=-2$

Apply formula for the $\sf n^{th}$ term of an arithmetic sequence.

$\sf a_n=a_1+dn-d$

$\sf a_1$ is the first term of the sequence.

$\sf d$ is the common difference.

$\sf a_n=18+-2n-(-2)$

$\sf a_n=18+-2n+2$

$\sf a_n=-2n+20$
