What does input and output mean

Answers

Answer 1

Answer:

Step-by-step explanation:

In mathematics, input and output are terms that relate to functions. Both the input and output of a function are variables, which means that they change. ... A simple example is y = x2 (which you can also write f(x) = x2). In such cases, x is the input and y is the output.

Question :-

A cylinder has a diameter of 4 cm and a height of 8.2 cm. What is the surface area of the cylinder?

Answer :-

The surface area of the cylinder is 128.112 cm². Thus, the 2nd option, B makes it as the correct answer.

Diagram :-

$\setlength{\unitlength}{1mm}\begin{picture}(5,5)\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\multiput(18,2)(0,32){2}{\sf{2 \: cm}}\put(9,17.5){\sf{8.2 \: cm}}\end{picture}$

Solution :-

As per the provided information in the given question, we have been given that the diameter of the cylinder is 4 cm. Thus, the radius of the cylinder is 2 cm. The height of the cylinder is 8.2 cm. We have been asked to find or calculate the surface area of the cylinder.

To calculate the surface area of the cylinder, we will use the formula below :-

$\bigstar \:\:\:\boxed{\sf{\:\:Surface \: Area_((Cylinder)) = 2\pi r^2 + 2\pi rh \:\:}}$

Substitute the given values into the above formula and solve for surfacearea:

$\sf:\implies Surface \: Area_((Cylinder)) = 2\pi r^2 + 2\pi rh$

$\sf:\implies Surface \: Area_((Cylinder)) = (2)(3.14)(2 \: cm)^2 + (2)(3.14)(2 \: cm)(8.2\:cm)$

$\sf:\implies Surface \: Area_((Cylinder)) = (2)(3.14)(4 \: cm^2) + (2)(3.14)(16.4\:cm^2)$

$\sf:\implies Surface \: Area_((Cylinder)) = (2)(12.56 \: cm^2) + (2)(51.496 \: cm^2)$

$\sf:\implies Surface \: Area_((Cylinder)) = 25.12 \: cm^2 + 102.992 \: cm^2$

$\sf:\implies \bf{Surface \: Area_((Cylinder)) = 128.112 \: cm^2}$

Therefore :-

The surface area of the cylinder is 128.112 cm². Thus, the 2ndoption, B makes it as the correctanswer.

Explain the difference between 9 square units and 9 cubic units

Answers

9 sq. units refers to a 2d figure
9 cubed units refers to a 3d figure

so
9*9 would be sq. unit cuz dimensions of square
9*9*9 would be cubed unit cuz dimensions of cube
so in simple, 9^2,
and 9^3

9 square units is basically 9 to the second power (9^2) while 9 cubic units is 9 cubed (9^3)

How to turn 6/3,5/3 & 8/3 into whole fractions

Answers

Divide the numerator by the denominator.
For the first one, 6 is the numerator. Divide it by 3 which is the denominator. And then only take the whole number from there.
6/3=2
5/3= 1.something but only take the 1
8/3=2.something but only take the 2
Because the whole fraction only wants the whole numbers.
Thanks :)

6/3 = 2
5/3= 1 2/3
8/3= 2 2/3
