Answer:

11,184,808

Step-by-step explanation:

The n-th term of a geometric series is ...

an = a1·r^(n-1)

To fill in the formula, we need a1·r^n, so need to multiply the last term shown by r.

The value of r is 32/8 = 4, and the other terms of interest are a1 = 8, a1·r^(n-1) = 8388608. So, the sum is ...

$S_n=\dfrac{ra_1r^{n-1}-a_1}{r-1}=\dfrac{4\cdot 8,388,608-8}{4-1}=11,184,808$

katrin [286]

Answer:

The number of sides the polygon have 9

Step-by-step explanation:

Given in question as :

For The circle , the central angles measure be 40 °

Let the number of sides of polygon = n

Now . as we know

External angle = $\frac{360^{\circ} }{n}$

Or , 40° = $\frac{360^{\circ} }{n}$

Or, $\frac{360^{\circ} }{n}$ = 40°

So, n = $\frac{360^{\circ} }{40^{\circ}}$ = 9

Hence The number of sides the polygon have 9 Answer
