Answer:
4π or about 12.56
Step-by-step explanation:
The circumference of a circle is calculated with diameter so we first need to find the diameter. Going from radius to diameter can be done by multiplying by 2, therefore 2*2=4 so the diameter is 4.
Now that we have the diameter we need to use the formula for circumference which is c=4*π. Because the question doesn't state to use 3.14 to multiply then you would usually use 4π as your answer but if you were to use 3.14 then you would get a circumference of 4*3.14=12.56.
The first thing we must do for this case is to find the conversion of rupees to US dollars.
Currently, the conversion is:
1 rupee = 0.014 $
Then, to find the amount of $ in 2000 rupees, we make the following rule of three:
1 rupee -----------------> 0.014 $
2000 rupees ----------> x
From here, we clear the value of x.
We have then:
Answer:
2,000 rupees are 28 US dollars.

Step-by-step explanation:
Tangent of 0 is always 0.
The equation relating the number of cars to the number of passengers is p = 4n
<em><u>Solution:</u></em>
Given that certain type of car has room for 4 passengers
To find: write an equation relating the number of cars to the number of passengers
Let "n" be the number of cars
Let "p" be the number of passengers
From given information,
Car has room for 4 passengers. Therefore, we can frame,
number of passengers = 4 ( number of cars )
p = 4 (n)
p = 4n
Thus the equation relating the number of cars to the number of passengers is p = 4n
