Answer:

Option (C)

Step-by-step explanation:

To determine the population we use the formula,

P_n=P_0(1+r)^{n}

Where P_n = final population

P_0 = Initial population

r = percentage growth

Now we substitute these values in the formula,

7921=7547(1+r)^1

\frac{7921}{7547}=(1+r)

r = 1.0496 - 1

r = 0.0496

r = 0.05

Therefore, percentage growth of the population of Stark county is 5%.

Option (C). will be the answer.

Answer:828.96m^2

Step-by-step explanation:

radius(r)=8m

L=25m

π=3.14

total surface area of cone(tsa)=πxr^2+πxrxL

Tsa=3.14x8^2+3.14x8x25

Tsa=3.14x8x8+3.14x8x25

Tsa=200.96 + 628

Tsa=828.96
