Answer:

<h2>62.832 mi.²</h2><h2></h2>

Step-by-step explanation:

surface area = 2πrh + 2πr²

where r = 2 miles radius

          h = 3 miles

<u>plugin values into the formula</u>

surface area = 2πrh + 2πr²

                     = 2π (2) 3  +  2π (2)²

                     = 37.699  +  25.133

                     = 62.832 mi.²

Answer:

They are only equal on day 0, both having 10 population.

Step-by-step explanation:

Given the bacteria on the counter is initially measured at 5 and doubles every 3 days we can generate the following geometric equation:

f(x)=10*2^{\frac{x}{3} }

Given the bacteria on the stove is measured at 10 and doubles every 4 days we can create another equation:

f(x)=10*2^{\frac{x}{4} }

To find how many days it will take for the bacteria population to equal the same lets set both equations equal to eachother:

10*2^{x/3}=10*2^{x/4}

Divide both sides by 10

2^{x/3}=2^{x/4}

Since both exponents have the same base we can set the exponents equal to eachother and solve for x:

\frac{x}{3}=\frac{x}{4}

Multiply both sides by 3 to isolate x on the left side

x=\frac{3x}{4}

Multiply both sides by 4 to remove fraction

4x=3x

Subtract 3x to isolate x on the left side

x=0

Plug x into one of our original equations

f(0)=10*2^{0/3}

Solve

f(0)=10
