if the height of cylinder 40cm and radius 10.5 find total surface and volume ​

Answers

Answer 1
Volume = 13,854.42 cm cubed (2 decimal places)
Surface Area = 3331.66 cm squared (2 decimal places
If The Height Of Cylinder 40cm And Radius 10.5 Find Total Surface And Volume
Answer 2

Answer:

TSA of cylinder= 2πrh+2πr²

(2*3.14*40*10.5)+(2*3.14*10.5*10.5)

= 2,638.93+692.72

= 3,331.66

Volume= πr²h

= 3.14*10.5*10.5*40

= 13,854.42

Which equation illustrates dividing out a common factor as the first step to solve the equation 2 x + 4 = 6 x + 2 ? A. 2 ( x + 2 ) = 2 ( 3 x + 1 ) B. 2 x 2 + 2 2 = 6 x 2 + 2 2 C. 2 x 2 + 4 = 6 x 2 + 2 D. 2 x + 4 2 = 6 x + 2 2

Answers

Answer:

Step-by-step explanation:

2x + 4 = 6x + 2

Bringing like terms on one side

4 - 2 = 6x - 4x

2 = 2x

the first two hours, but then the first guy left to help another mechanic on
a different job. How long will it take the new guy to finish your car?

Answers

I hope this is right, but I think it should take a remaining six hours for the new guy to fix your car. He worked on it for two hours with the other mechanic, but it still takes him 8 hours total to fix the car. So he still has six more hours to fix your car. Again, I hope this is right.

Figure 4: 33 units²

Figure 5: 25 units²

Figure 6: 30 units²

Figure 7: 25 units²

Figure 8: 32 units²

Reasons:

Figure 3 consists of 2 shapes, A rectangle and a square

                  ████████                                           ◣

rectangle: ████████            triangle:               █◣

                   ████████                                          ██◣

rectangle:

to calculate a rectangle's area: multiply the lengths of the width and height:

████████= width  8           █

                                                █    =height 3

                                                █

[tex]area=w(h)[/tex]

now substitute the values of W and H:

[tex]8(3)=24[/tex]

rectangle area = 24

Triangle:

to find the area of a triangle, multiply the width and height and divide by two:

◣ + ◣ = █         0.5 + 0.5 = 1

                                                █    

███=width   3                         █ =height  3

                                                █    

               

[tex]area=\frac{w(h)}{2}[/tex]

now substitute W and H

[tex]area=\frac{3(3)}{2}[/tex]

[tex]area\frac{9}{2}[/tex]

Triangle area: 4.5

Now add the Rectangle Area To the triangle Area:

4.5 + 24 = 28.5

Final answer:

AREA =2 8.5

Answer:

x = 4, x = 8

Step-by-step explanation:

Given 2 secants from an external point to the circle, then

The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is

x(x + 6) = 5(5 + 3)

x² + 6x = 5 × 8 = 40 ( subtract 40 from both sides )

x² + 6x - 40 = 0 ← in standard form

(x + 10)(x - 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 10 = 0 ⇒ x = - 10

x - 4 = 0 ⇒ x = 4

x > 0 then x = 4

(11)

Given a secant and a tangent from an external point to the circle, then

The square of the tangent is equal to the product of the external part and the whole of the secant, that is

x(x + 10) = 12²

x² + 10x = 144 ( subtract 144 from both sides )

x² + 10x - 144 = 0 ← in standard form

(x + 18)(x - 8) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 18 = 0 ⇒ x = - 18

x - 8 = 0 ⇒ x = 8

x > 0 then x = 8

List the steps in order you used to evaluate 6(x-5) when substituting x=8. Can you think of a different way to solve 6(x-5)=18 based on reversing these steps? * 15 Points)​

Answers

So we can do 6(x-5)=18 and then divide 18 by 6 so we take the 6 in the equation and divide that by 6. So then the equation is x-5=3 and then x equals 8
