<h3>Answer:  75.36 square feet</h3>

Your teacher may want you to type the number only.

==========================================================

Work Shown:

SA = surface area of a cylinder

SA = 2*pi*r^2 + 2*pi*r*h

SA = 2*3.14*2^2 + 2*3.14*2*4

SA = 75.36

The surface area is roughly 75.36 square feet.

(6,3*10^-2)÷(2,1*10^4​
nexus9112 [7]

Answer:

  • 3*10^{-6} or 0.000003

Given expression:

  • (6.3*10^{-2}) : (2.1*10^4)

Simplify it in steps below:

  • (6.3*10^{-2}) : (2.1*10^4) =
  • (6.3 :2.1)*(10^{-2}:10^4)=
  • 3*(10^{-2-4})=
  • 3*10^{-6} or 0.000003

<u>Used properties:</u>

\cfrac{ab}{cd}=\cfrac{a}{c}*\cfrac{b}{d}

a^b:a^c=a^{b-c}

a^{-b}=1/a^b

Polygon D is a scaled copy of polygon C using a scale factors of 6
Vladimir79 [104]

Answer: The area of the Polygon D is 36 times larger than the area of the Polygon C.

Step-by-step explanation:

<h3> The complete exercise is: "Polygon D is a scaled copy of Polygon C using a scale factor of 6. How many times larger is the area of Polygon D than the area Polygon C"?</h3>

 In order to solve this problem it is important to analize the information provided in the exercise.

You know that the Polygon D was obtained by multiplying the lengths of the Polygon C by the scale factor of 6.

Then, you can identify that the Length scale factor used is:

Length\ scale\ factor=k=6

Now you have to find the Area scale factor.

Knowing that the Length scale factos is 6, you can say that the Area scale factor is:

Area \ scale\ factor=k^2=6^2

Finally, evaluating, you get that this is:

Area \ scale\ factor=36

Therefore, knowing the Area scale factor, you can determine that the area of the Polygon D is 36 times larger than the area of the Polygon C.
