Answer: Letter Choice, (B) ====> 4,256 pi cm^2

Step-by-step explanation:

Formula: Surface Area of Cylinder = (2pi ) (r^2 ) + 2pi (r) (h)

Showing Work:

Radius of the Base ===> 28cm

Height =====> 48cm 

(2pi ) (r^2) + 2pi (28)(48)

2 (pi) (r^2) + (circumference) (height)

2( pi) (r^2 + 2)( pi)(r)(h)

2 pi * (2) (r^2 + (2)(r)(h)

2pi * (r^2 + rh)

2(r)(pi)(r + h)

2( 28)(pi)(28 + 48)

56(pi)(76)

4256(pi)^2

Therefore, Your Answer ======> Letter Choice; (B) ======> 4,256pi cm^2

Hope that helps!!!!! : )

Find the sum of the first 8 terms of the series. 1/2 + 1 + 2 + 4

Roman55 [17]

$\bf \cfrac{1}{2}~~,~~\stackrel{2\cdot \frac{1}{2}}{1}~~,~~\stackrel{2\cdot 1}{2}~~,~~\stackrel{2\cdot 2}{4}~~,...$

so as you can see the common ratio is 2, and the first term is 1/2,

$\bf \qquad \qquad \textit{sum of a finite geometric sequence} \\\\ S_n=\sum\limits_{i=1}^{n}\ a_1\cdot r^{i-1}\implies S_n=a_1\left( \cfrac{1-r^n}{1-r} \right)\quad \begin{cases} n=n^{th}\ term\\ a_1=\textit{first term's value}\\ r=\textit{common ratio}\\ ----------\\ r=2\\ a_1=\frac{1}{2}\\ n=8 \end{cases} \\\\\\ S_8=\cfrac{1}{2}\left( \cfrac{1-2^8}{1-2} \right)\implies S_8=\cfrac{1}{2}\left( \cfrac{-255}{-1} \right)\implies S_8=\cfrac{255}{2}$
