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
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

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
