Answer:

c) 345.4 cm²

The  plastic coating would be needed to coat the surface of the chain link

                      = 345.4 cm²  

Step-by-step explanation:

<em>Given radius of the cylinder 'r' = 2.5 cm</em>

<em>Given Height of the cylinder 'h' = 22 cm</em>

<em>Area of the curved surface =  2 π r h </em>

<em>The plastic coating would be needed to coat the surface of the chain link</em>

<em>                   A =  2 π r h </em>

<em>                  A =  2 × 3.14 ×2.5×22 </em>

<em>                 A   = 345.4 cm²</em>

<u><em>Conclusion</em></u><em>:-</em>

<em>The  plastic coating would be needed to coat the surface of the chain link</em>

<em>                       = 345.4 cm²</em>

Find the 8th term of the geometric sequence 5, -15, 45
FrozenT [24]

Answer:

a₈ = - 10935

Step-by-step explanation:

the nth term of a geometric sequence is

a_{n} = a₁ (r)^{n-1}

where a₁ is the first term and r the common ratio

here a₁ = 5 and r = \frac{a_{2} }{a_{1} } = \frac{-15}{5} = - 3 , then

a₈ = 5 × (-3)^{7} = 5 × - 2187 = - 10935

Please answer question plz!!!!!
Neporo4naja [7]

Answer:

V = 214.32

Step-by-step explanation:

Remark

You have to be a little careful with this question. The temptation is just to take the difference of the heights. That is not correct. The difference has to be multiplied by the base to get the volume.

Formula

V = (h1 - h2)* Base

Givens

h1 = 32.9

h2 = 29.1

Base = 56.4

Solution

V = 56.4 ( 32.9 - 29.2)

V = 56.4 * 3.8

V = 214.32
