Manuel incorrectly claimed that the surface area of the cylinder

Andre45 [30]

Answer:

25.9%

Step-by-step explanation:

Since, the actual dimensions of the cylinder is not given we can assume the some dimension to explain the problem

Let us assume the dimension of the cylinder be

radius= 3in

height= 5 in

The expression for the total surface area of a cylinder is

T. S. A. =2πrh+2πr^2

Let us plug in the values to to find TSA

T. S. A. =2×3.14×3×5+2×3.14×3^2

Solving we get

T. S. A. =94.26+56.556

T. S. A. =150.816 in^2

Now let us find the error

we know that error % is calculated as

%error= [actual value-expected value/expected value]×100

%error= [190 -150.816/150.816]×100

%error= [39.184/150.816]×100

%error= 0.259×100

%error= 25.9%

Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 8 liters of natural oil for every 5 liters of

Ludmilka [50]

Answer: 370 liters

Step-by-step explanation:

Given : Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 8 liters of natural oil for every 5 liters of synthetic oil.

Then , the amount of Petrolyn oil made by above composition = $8+5=13\text{ liters}$

Also, the amount of petrolyn oil is proportional to the amount of synthetic oil.

Let x be the amount of synthetic oil need ot make 962 liters of Petrolyn oil, the we have the following equation:-

$\dfrac{x}{962}=\dfrac{5}{13}\\\\\Rightarrow\ x=\dfrac{5\times962}{13}=370$

Hence, In order to make 962 liters of Petrolyn oil, 370 liters of synthetic oil is needed .
