Answer:

b. 777.54 square meters

Step-by-step explanation:

<em>Total surface area of cylinder = 2 π r(r+ h)</em>

<u>Given:</u>

d = 15 m ⇒ r = 15 m/2 = 7.5 m
h = 9 m

2 π r(r+ h) = 2π*7.5*(7.5 + 9) ≈ 777.54 m²

Correct answer choice is b. 777.54 square meters

What is the 8th term of the geometric sequence 8,16,32

ratelena [41]

the 8th term of the geometric sequence 8, 16, 32 is 1024

<h2>Explanation</h2>

geometric sequence 8, 16, 32

<u>the </u><u>question</u><u> </u><u>is</u>

the 8th term

<u>the </u><u>answer </u><u>is</u>

first we have to find the ratio

$\sf r= \frac{ U_2}{U_1} \\ \sf r= \frac{ 16}{8} \\ \sf r = 2$

than, we have to find the 8th term

$\sf U_n = ar^{n-1} \\ \sf U_8 = 8 \times 2^{8-1} \\ \sf U_8 = 8 \times 2^7 \\ \sf U_8 = 8 \times 128 \\ \bold {\sf U_8 = 1024}$
