Answer:

<u>6</u><u>6</u><u>0</u><u>0</u><u>f</u><u>t</u><u>.</u><u>²</u> is the correct answer.

Step-by-step explanation:

Given that,

  • Diameter of the Cylindrical tank, d = 60 ft
  • Height of the Cylindrical tank, h = 20 ft
  • Radius of the Cylindrical tank, r = <u>3</u><u>0</u><u>f</u><u>t</u><u>.</u>

\:

To Find:

  • Area of the Cylindrical tank to be painted.

\:

Solution:

Area of Cylindrical tank to be painted = CSA of the Cylindrical tank + Area of the circle

\star \quad{ \boxed{ \green{CSA_{(Cylinder)} = 2 \pi r h }}} \quad \star

\star \quad{ \boxed{ \green{Area_{(Circle)} = \pi {r}^{2}  }}} \quad \star

\longrightarrow \: 2\pi rh \:  + \pi {r}^{2}

\longrightarrow \: \pi r(2h + r)

\longrightarrow \: \frac{22}{7} \times 30 \times(2\times20+30)

\longrightarrow \:  \frac{660}{7}  \times (40 + 30)

\longrightarrow \:  \frac{660}{7} \times 70

\longrightarrow \:  660 \times 10

\longrightarrow \: 6600 {ft.}^{2}

Hence, Area of the Cylindrical tank to be painted is <u>6600ft.²</u>

Write -2x^2 (-5x^2 + 4x^3) in standard form
saul85 [17]
-2x·-2x·(-5x·-5x+4x·4x·4x) Basically, you write out the number depending on the exponent. So if you have a power/exponent of 3, you write it out multiplied by itself 3 times. Hope this helps!

What is the median of the data set?
gizmo_the_mogwai [7]
7. because you would put the number set into order from least to greatest first, ti would look like this: 2,3,4,5,9,10,12,12. then go to the middle, crossing one from each side off at one time. Then you get 5 and 9 in the middle. Then the middle between 5 and 9 is seven, you can check this by: 5+9=14, then 14/2= 7.
Your median is 7.
