Answer: the answer is 175.84

Step-by-step explanation: TSA of cylinder= pir( r + h)

= 3.14 x 4 x ( 4 + 10 )      {here diameter is 8 so radius is it's half}

= 3.14 x 4 x 14

= 175.84

Answer:

by using the formula of 2×22/7×r (r+h)

Answer: A

Step-by-step explanation:

17 is your answer

Because different between the x and 13 is equal to the 9 and 13 as shown in diagram

we can write equation

13-9 = x-13

4=x-13

x= 13+4 = 17 Ans

Integration Methods: U-Substitution and U-Solve

Special Integrals:

Step-by-step explanation:

*Note:
The problem is too big to fit all work. I will assume that you know how to do basic calculus.

Step 1: Define

Identify given.

[tex]\displaystyle \int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx[/tex]

Step 2: Integrate Pt. 1

Step 3: Integrate Pt. 2

Identify variables for u-substitution.

Step 4: Integrate Pt. 3

Step 5: Integrate Pt. 4

Identify variables for u-substitution for the 1st integral.

Use another variable besides u to avoid confusion with earlier substitutions.

Step 6: Integrate Pt. 5

Solve the 1st integral using basic integration techniques listed under "Calculus":
[tex]\displaystyle \begin{aligned}\int\limits^{x = 1}_{x = 4} {\cos (u - e)} \, du & = \int\limits^{x = 1}_{x = 4} {\cos v} \, dv \\& = \sin v \bigg| \limits^{x = 1}_{x = 4} \\& = \sin (u - e) \bigg| \limits^{x = 1}_{x = 4} \\& = \sin (x) \bigg| \limits^{x = 1}_{x = 4} \\& = \sin 1 - \sin 4\end{aligned}[/tex]

Step 7: Integrate Pt. 6

To solve the 2nd integral, we use the same methods as "Step 6":

[tex]\displaystyle\begin{aligned}\int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du & = \int\limits^{x = 1}_{x = 4} {\frac{\sin e \sin u + \cos e \cos u}{u}} \, du \\& = \sin e \int\limits^{x = 1}_{x = 4} {\frac{\sin u}{u}} \, du + \cos e \int\limits^{x = 1}_{x = 4} {\frac{\cos u}{u}} \, du \\& = \sin (e) \text{Si} (u) \bigg| \limits^{x = 1}_{x = 4} + \cos (e) \text{Ci} (u) \bigg| \limits^{x = 1}_{x = 4} \\\end{aligned}[/tex]

[tex]\displaystyle\begin{aligned}\int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du & = \sin (e) \text{Si} (x + e) \bigg| \limits^{x = 1}_{x = 4} + \cos (e) \text{Ci} (x + e) \bigg| \limits^{x = 1}_{x = 4} \\& = \bigg[ \sin (e) \text{Si} (1 + e) - \sin (e) \text{Si} (4 + e) \bigg] + \bigg[ \cos (e) \text{Ci} (1 + e) - \cos (e) \text{Ci} (4 + e) \bigg] \\\end{aligned}[/tex]

Step 8: Integrate Pt. 7

Combine our 2 integral values to obtain a final answer:

[tex]\displaystyle \int\limits^1_4 {\frac{\cos x}{1 + \frac{e}{x}}} \, dx & = \int\limits^{x = 1}_{x = 4} {\cos ( u - e)} \, du - e \int\limits^{x = 1}_{x = 4} {\frac{\cos (u - e)}{u}} \, du \\\begin{aligned}& = \sin 1 - \sin 4 - e \bigg[ \sin (e) \text{Si} (1 + e) - \sin (e) \text{Si} (4 + e) + \cos (e) \text{Ci} (1 + e) - \cos (e) \text{Ci} (4 + e) \bigg] \\& \approx \boxed{0862854} \\\end{aligned}[/tex]

∴ we have evaluated the given special definite integral.

Answer:

[tex]x=\dfrac{131}{333}[/tex]

Step-by-step explanation:

Assign the decimal to a variable:

Let  [tex]x=0.\overline{393}[/tex]

Multiply both sides by 1000:

[tex]\implies x \cdot 1000=0.\overline{393} \cdot 1000[/tex]

[tex]\implies 1000x=393.\overline{393}[/tex]

Subtract the first equation from the second to eliminate the part after the decimal:

[tex]\begin{array}{r r c r}& 1000x & = & 393.\overline{393} \\\\- & x & = & 0.\overline{393} \\\\\cline{2-4} \\& 999x & = & 393 \\\end{array}[/tex]

Divide both sides by 999:

[tex]\implies \dfrac{999x}{999}=\dfrac{393}{999}[/tex]

[tex]\implies x=\dfrac{393}{999}[/tex]

Reduce the fraction:

[tex]\implies x=\dfrac{393 \div 3}{999 \div 3}[/tex]

[tex]\implies x=\dfrac{131}{333}[/tex]

Find 20% of 200

For fraction: divide 20 by 100 and remove the % sign.

[tex]{20}\%=\frac{20}{100}[/tex]

For decimal: move the decimal point 2 places to the left and remove the % sign.

[tex]{20}\%=0.2[/tex]

Multiply the decimal or fraction by the quantity that equals 100%

[tex]100[/tex]%[tex]=200[/tex]

[tex]\frac{20}{100} *200=0.2*200=40[/tex]

20% of 200 is 40

Divide the arrow into upper triangle and lower rectangle

area of triangle :-

[tex] \frac{1}{2} \times base \times height[/tex]

[tex] \frac{1}{2} \times 20 \times (15 + 8 + 8) \\ \frac{1}{2} \times 20 \times 31 = 310[/tex]

area of rectangle :-

[tex]length \: \times \: width \\ 15 \times 20 = 300[/tex]

add both the area :-

area of triangle+ area of rectangle = area of arrow

310 + 300 = 610 cm²
