We solve for the diameters of radius of the given circles by using the equation,
                                      C = πD
                    or               C = 2πr
where D and r are diameter and radius, respectively.

Solving,
      C = 34.54 units
                                D = C/π = 34.54 units / 3.14 = 11 units
                                r = C / 2π = 34.54 units/2(3.14) = 5.5 units

      C = 59.66 units
                                D = C/π  = 59.66 units/3.14 = 19 units
                                 r = D2 = 9.5 units
      C = 23.236 units
                                D = 23.236 units/3.14 = 7.4 units
                                 r = D/2 = 3.7 units
       C = 23.376 units
                                 D = 23.376 units / 3.14 = 7.4 units
                                    r = D/2 = 3.7 units
        C = 13.188 units
                                  D = 13.188 units/3.14 = 4.2 units
                                    r = D/2 = 2.1 units

The population of a county is growing at a rate of 9% per year, compounded continuously. How many years will it take for the pop
torisob [31]

Answer:

t=15.4\ years

Step-by-step explanation:

The  exponential growth function compounded continuously is equal to

A=P(e)^{rt}  

where  

A is the final population  

P is the initial population  

r is the rate of growth in decimal  

t is Number of years

e is the mathematical constant number

we have  

A=4x\\P=x\\ r=9\%=9/100=0.09  

substitute in the function above

4x=x(e)^{0.09t}    

simplify

4=(e)^{0.09t}

Take natural log of both sides

ln(4)=ln[(e)^{0.09t}]

ln(4)=0.09t(ln(e))

ln(e)=1

ln(4)=0.09t

t=ln(4)/0.09

t=15.4\ years

Find the area of a circle whose area equals the half of the sum of the areas of two circles with radil 2 and 3.
OlgaM077 [116]

Step-by-step explanation:

step 1. a circle with r = 2 has area of (pi)r^2 = (pi)(4) = 4pi

step 2. a circle with r = 3 has area of (pi)r^2 = (pi)(9) = 9pi

step 3. the area, A, of a circle is half the sum of the area of the circles with r = 2 and r = 3

step 4. A = (4pi + 9pi)/2 = 13pi/2 = 6.5(pi).

step 5. the answer is not 6.5 but is 6.5(pi) or 6.5 times pi.

Rita has the following data:
Lubov Fominskaja [6]
The range is the difference between the largest number and the smallest number. This means you subtract the smallest number from the largest number. If the range is 8, then you can add 8 to the smallest number on the list to get the largest number, m.
Our smallest number is 12, so add 8 to 12.
8 + 12 = 20, so m is 20.
I hope this helps!
