Manuel incorrectly claimed that the surface area of the cylinder shown is about 190.0 in.2. Use a formula to find the surface ar
Kitty [74]

Answer:

25.9%

Step-by-step explanation:

Note: you did not provide any attached image detailing the dimension of the cylinder however, let us arrange some dimension for explanation purpose

let the dimension of the cylinder be

radius= 3in

height= 5 in

Step two

The expression for the total surface area of a cylinder is

T. S. A. =2πrh+2πr2

substitute

T. S. A. =2*3.142*3*5+2*3.142*3^2

T. S. A. =94.26+56.556

T. S. A. =150.816 in^2

Now let us find the error

%error= actual -expected/expected*100

%error= 190 -150.816/150.816*100

%error= 39.184/150.816*100

%error= 0.259*100

%error= 25.9%

Now, you can use the dimension you have for the cylinder to calculate the total surface area, from there, you can solve for the error by following the steps above

Suppose that y varies directly as the square root of x, and that y=21 when x=361. What is y when x=247? (Round off your answer t
igomit [66]

Answer:

17.37

Step-by-step explanation:

y varies inversely as the square root of x

Mathematically:

y = k.root x

We first find k here

To find k, we were made to know that y is 21 and x = 361

k = y/root.x

k = 21/root. 361

k = 21/19

now what is y when x = 247

From y = k.root x

y = 21/19 * root 247

y= 21/19 * 15.72

y = 17.37

Z= 3 - 2x + 4(z - 8) when z = 18
wlad13 [49]

Answer:

25/2

Step-by-step explanation:

Let's solve your equation step-by-step.

18=3−2x+4(18−8)

Step 1: Simplify both sides of the equation.

18=3−2x+4(18−8)

18=3+−2x+40

18=(−2x)+(3+40)(Combine Like Terms)

18=−2x+43

18=−2x+43

Step 2: Flip the equation.

−2x+43=18

Step 3: Subtract 43 from both sides.

−2x+43−43=18−43

−2x=−25

Step 4: Divide both sides by -2.

−2x

−2

=

−25

x=

Answer:

x=
