Answer:
<h3>Therefore the sum if the series is 15.98!</h3>
The common ratio is 1/2 or 0.5 . If you multiply the current term by the the common ratio the the output will be the next term.
8⋅1/2=4
4⋅1/2=2
2⋅1/2=1 etc ...
because the absolute value of r is less than 1 we can use the following formula.
a/1−r where a is the first term and r is the common ratio
In our problem
a=8 and r=0.5
Substitute
8/1−0.5=8/0.5=16
The sum of this infinite geometric series is 16.
Also, another formula you can use that is guaranteed to work every time, no matter what, is:
Sn=a(r^n−1/r−1)
All the variables work the same way as above, and "n" is the number of terms in the series. So, say you wanted to find the sum of the first 10 terms and were to substitute everything in:
S10=8(0.5^10−1/0.5−1)
S10=15.984375
Therefore the sum if the series is 15.98!

Answer:
32672.64 pounds
Step-by-step explanation:
Diameter = 10ft
Radius = d / 2 = 10 / 2 = 5ft
Density (p) = 62.4 pounds/ft³
Volume of a hemisphere = 4/3Πr³
V = 4/3 * π * 5³
V = 4/3 * 392.7
v = 523.6ft³
but density ρ = mass / volume
mass = density * volume
Mass = 62.4 * 532.6
Mass = 32672.64pounds
The weight of the water in full tank is 32672.64 pounds
