We know that
in a unit circle the radius is 1
therefore
[Length of a circumference]=2*pi*r------> 2*pi

if 2pi radians in a circle unit has a length of ------------> 2*pi
2pi/3 radians----------------------------> X
X=2pi/3

the answer is 2pi/3

The correct answer is:

2π/3.

Explanation:

An angle formed on the unit circle would be a central angle.

The measure of an intercepted arc is the same as the measure of the central angle; since the angle is 2π/3, the arc length is 2π/3.

A population of 110,000 grows 3% per years 15 years. How much will the population. How much will the population be after 15 year

bonufazy [111]

Answer:

The population be after 15 years is 171376.

Step-by-step explanation:

Given : A population of 110,000 grows 3% per years 15 years.

To find : How much will the population be after 15 years?

Solution :

Exponential growth population model is given by,

$P(t)=P_o(1+r)^t$

Where,

P(t) is the population at time (t)

$P_o=110,000$ is the initial value of the population

r=3%=0.03 is the annual rate of growth

t=15 is the time in years.

Substitute the value,

$P(t)=110000(1+0.03)^{15}$

$P(t)=110000(1.03)^{15}$

$P(t)=110000\times 1.5579$

$P(t)=171376.41$

Therefore, the population be after 15 years is 171376.

PLEASE HELP In 2010 the population of India was 1,231,000,000. By 2016, the population had increased by 7.5%.The land area of In

PtichkaEL [24]

Answer:

The population density of India in 2016 was of 1042.8 habitants per miles squared.

Step-by-step explanation:

Population density:

Number of habitants divided by land area.

In 2010 the population of India was 1,231,000,000. By 2016, the population had increased by 7.5%.

This means that India's population in 2016 was given by:

1,231,000,000*1.075 = 1,323,325,000

The land area of India is 1, 269,000 miles squared:

1,323,325,000/1,269,000 = 1042.8 habitants per miles squared.

The population density of India in 2016 was of 1042.8 habitants per miles squared.
