Answer: Ratio of circumference of a circle to its diameter is 22:7.

Step-by-step explanation:

Since we have given that

Radius of circle = 5

Diameter of circle = 10

As we know the formula for "Circumference of circle":

Circumference of circle is given by

2\pi r

Hence, ratio of circumference of circle to its diameter is given by

Circumference:Diameter\\\\2\pi r:2r\\\\\pi:1\\\\22:7

<span>π = C / 10    ( the is 10 because  diameter = 2 * radius)</span>

Answer:

$1480.24

Step-by-step explanation:

This will be solved by the formula:

FV=I(1+r)^t

Where

FV is the future value (what we are looking for)

I is the initial amount (which is $1000)

r is the rate of interest per period (8% is annual interest, but the period is SEMI-ANNUAL, that's 6 months, half of yearly. So r would be half of 8%, which is 4% or r = 0.04)

t is the times compounding occurs in the whole time (The whole time period is 5 years, but compounding occurs semi-annually, so 5*2 = 10 times. Thus, t = 10)

<em>plugging the info into the formula we will get our answer.</em>

<em>FV=I(1+r)^t\\FV=1000(1+0.04)^{10}\\FV=1000(1.04)^{10}\\FV=1480.24</em>

The population (in millions) of a certain country can be approximated by the
Agata [3.3K]

Answer:

year 2343

Step-by-step explanation:

The population (in millions) of a certain country can be approximated by the

function:

P(x) = (100)*1.02^(x)

where x is the number of years after 2000.

If we want a population of 300 million

300.10^6 = (100)*1.02^(x)

3.10^6 = 1.02^(x)

Which can be solved with a calculator or any computational tool. See attached pictures

The answer is

x = 342.804

2000 + 342.804 = 2342.804 ≈ 2343

How is a change in the circumference of a circle related to the diameter of a circle
zaharov [31]

Answer:

let's use c as circumference, d for diameter

lets say c increases, d is related to c, d will also increase

if c decreases, d will too.

Let's put in this way.

Pretend you're at a store,

The more you spend, the more points you get in their loyalty program

C is going to be the amount you spend

D will be how many points you get

Spend more, more points

spend less, less points

P.S

C is the independent variable, D is the dependent variable. (I think that's the right way, if not ignore the postscript aka P.S)
