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>

Look at the parallelogram below. Ð1 and Ð3 are each 35°. What is the measurement of Ð2?
m_a_m_a [10]
The interior angel for this parallelogram is 360° because
180°(n-2) where n represent the total side.
Angle 1+ Angle 3=70°
360°-70°=290°
290°÷2=145°. As a result, the measurements of D2 is D. Hope it help!
