Answer:

Option A = 113.04in^2

Step-by-step explanation:

Question: What is the total surface area of the cylinder? If the radius is 2in and height is 7in.

A) 113.04 in.2

B) 100.48 in.2

C) 131.88 in.2

D) 69.08 in.2

Solution:

Total surface area of a cylinder = 2πr^2 + 2πrh

r = radius = 2in

h = height = 7in

Let π = 3.14

Total surface area of the cylinder =

2×π×2^2 + 2×π×2×7

= 8π + π×28

= 8×3.14 + 3.14×28

Total surface area of the cylinder = 113.04in^2

=113.04in^2 (option A)

⦁ The population of the Tallahassee metropolitan area was 382,627 at the end of 2017 with a growth rate of 2.78%. Using the expo

a_sh-v [17]

Answer:

The exponential growth model for the population of the Tallahassee metropolitan area is $y=382627(1.0278)^t$ .

Step-by-step explanation:

The exponential formula is

$y=b(1+r)^t$

Where b is initial population, r is growth rate, (1+r) is growth factor and t is time (in years) after the initial year.

The population of the Tallahassee metropolitan area was 382,627 at the end of 2017. The growth rate is 2.78%.

Here the initial year is 2017 and rate is 0.0278

$y=382627(1+0.0278)^t$

$y=382627(1.0278)^t$

Graph of the equation is shown below. The x-axis represents the number of years after 2017 and y-axis represents the total population.

Difference between 2025 and 2017 is 8 years. Put t=8

$y=382627(1.0278)^8$

$y=476479.828188\approx 476479$

Therefore the projected population in 2025 is 476479.

Why is the grid in Example 1 a good way to<br> represent a percent?

Tems11 [23]

Answer:

percent means <u>per hundred </u>

Between the 100 squares, 60 of them are shaded

so you do 60/100

it's kind of like correcting tests, you have 100 questions, you got 80 of them right so its going to be 80/100

when you calculate percentage, you do the fraction x 100

so it's 60/100 = 0.6 x100 = 60%

hope that answers your question
