Answer:
The sum of the first 8 terms in the series is 65535.
Step-by-step explanation:
We have,
The common ratio in a geometric series, r = 4
First term of GP is, a = 3
It is required to find the sum of the first 8 terms in the series. The sum of first n terms of a GP is given by :

Here, n = 8

So, the sum of the first 8 terms in the series is 65535.
I csn help for the first one can't help with the colunms the answer is 1,396.

52.38 inch² & 261.90 inch²

<u>Step-by-step explanation:</u></h3>
Here we need to find the area of the sector . So according to formula we know the area of sector as ,
Here we can see that the central angle subtended by the arc is 60° and the radius of the circle is 10 inches . So the required area would be ,
=> Area = ∅/ 360° × π r²
=> Area = 60°/360° × 22/7 × (10in.)²
=> Area = 1/6 * 22/7 * 100 in²
=> Area = 52 .380 in²
<h3>
<u>★</u><u> </u><u>Hence </u><u>the </u><u>area </u><u>o</u><u>f </u><u>the </u><u>red</u><u> </u><u>sector </u><u>is </u><u>5</u><u>2</u><u>.</u><u>3</u><u>8</u><u> </u><u>inch²</u><u>.</u></h3>

Now let's find out the area of blue sector .The angle subtended by the arc will be (360-60)°=300° .
=> Area = 300/360 × 22/7 × 100 in²
=> Area = 261. 90 in²
<h3>
<u>★</u><u> </u><u>H</u><u>ence </u><u>the </u><u>area </u><u>of </u><u>blue </u><u>sector </u><u>is </u><u>2</u><u>6</u><u>1</u><u>.</u><u>9</u><u>0</u><u> </u><u>inch</u><u>²</u><u>.</u></h3>


I'll just have to do manual computation per throw.
1) 3
2) 2.4
3) 1.92
4) 1.92 * 0.80 = 1.536
5) 1.536 * 0.80 = 1.2288
6) 1.2288 * 0.80 = 0.9830
7) 0.9830 * 0.80 = 0.7864
8) 0.7864 * 0.80 = 0.6291
9) 0.6291 * 0.80 = 0.5033
10)0.5033 * 0.80 = 0.4026
sum of all tries is 13.3892 or A) 13.39 feet
