Find area of each surface:

8 in*9 in=72 in^2

15 in*9 in=135 in^2

17 in*9 in=153 in^2

then, add up all the numbers:

72+135+153=360 in^3

Answer:

64 $\pi$ mm² or approximately 201.06 mm²

Step-by-step explanation:

If the diameter is 16 mm, the radius will be 8 mm.

Use the circle area formula, A = $\pi$ r², where r is the radius. Plug in 8 as r:

A = $\pi$ r²

A = $\pi$ (8²)

A = 64 $\pi$

So, the area of the circle is 64 $\pi$ mm² or approximately 201.06 mm²

The sum of the first n terms of an arithmetic sequence is n/2(4n + 20).

lesantik [10]

Answer:

(a).

$S_{n} = \frac{n}{2} (4n + 20) \\ \\S _{n - 1} = \frac{(n - 1)}{2} (4n - 4 + 20) \\ \\ S _{n - 1} = \frac{(n - 1)}{2} (4n + 16) \\ \\S _{n - 1} = \frac{(n - 1)(4n + 16)}{2} \\ \\ { \boxed{S _{n - 1} = {2 {n}^{2} + 6n - 8}}} \\$

(b).

from general equation:

$S _{n - 1} = \frac{(n - 1)}{2} (4n + 16)$

first term is 4n

common difference:

$16 = \{(n - 1) - 1 \}d \\ 16 = (n - 2)d \\ d = \frac{16}{n - 2}$
