Exponential Growth problem.
xxMikexx [17]
It will be understood that population 6,000 billion (6*10^12) in 2017.
If this is not the case, follow the logic and the final number can be adjusted easily.

Mathematical answer:
In 2017: 6,000 billion=6000*10^9 =6*10^12
rate of increase = 1.3% per year (assumed constant)
final year = 2100
Population estimate in 2100
=6*10^12*(1.013^(2100-2017))
=6*10^12*(1.013^(83)
=6*10^12*(2.921352509198383)
=17.528*10^12
=17,528 billion.

this circle has a diameter of 5 inches which of these measurements is closest to the circumference of the circle 15.7 7.85 31.4
nirvana33 [79]

Answer:

The closest measurement is 15.7

Step-by-step explanation:

The formula for circumference is 2\pi r

The diameter is double the radius, so to get the radius we divide by 2.

5 divided by 2 is 2.5

Knowing "r" is 2.5 we can plug that into our equation and solve.

2 · \pi · 2.5 ≈ 15.71

The closest measurement is 15.7
