Find the Surface Area of a cylinder with a base radius of 2 cm and a height of 3 cm. Use pi = 3.14

Answers

Answer 1

Answer: $A_S=2\pi r^2+2\pi rH\n\nr=2cm;\ H=3cm\n\nA_S=2\pi\cdot2^2+2\pi\cdot2\cdot3=2\pi\cdot4+2\pi\cdot6=8\pi+12\pi=20\pi\ (cm^2)\n\n20\pi\approx20\cdot3.14=62.8\ (cm^2)$

Answer 2

Answer: $S=2\pi r(r+h)\n S=2\cdot3.14\cdot2\cdot(2+3)\n S=12.56\cdot5\n S=62.8\ cm^2$

Is y+6x=-14 quadratic?

Answers

normally it is a function where you have y=output or f(x)

minus 6x
y=-6x-14
f(x)=-6x-14

quadratic functions are second degree, meaning they have x^2 as hiehgest exponnet

the highest is x^1

it is NOT quadratic

no, because it doen't follow the quadratic equation formula.

The following points that are on the line given by the equation y=2x are Options (D). (3,6) and (F). (5,10).

What is a straight line ?

A straight line is a line passing through the x-y plane that has equal intercepts with respect to the x axis and the y-axis. The slope of a straight line is always equal. The straight line is also satisfied by the coordinates points in the x and y axis respectively.

How to identify the points on the given line y = 2x ?

To identify the points satisfied by any given equation, we have to replace the points given in the following equation.

Taking first point in option (A) , (16,8) , we have y = 8 and x = 16 which does not satisfy the equation y = 2x .

Taking second point in option (B) , (1,3) , we have y = 3 and x = 1 which does not satisfy the equation y = 2x .

Now from the following options, checking points in Option (D) where x = 3 and y = 6 which satisfies the equation y = 2x .

Also checking the points in Option (F) where x = 5 and y = 10 which satisfies the equation y = 2x .

The following points that are on the line given by the equation y=2x are Option(D). (3,6) and Option(F). (5,10) .

Divide: (x^2-10x+30)/(x-5)A. x-10-6
B. x-5- 5/x-5
C. x-10- 30/x-5
D. x-5+ 5/x-5

Answers

Answer:

Option D is correct.

Step-by-step explanation:

$(x^(2) -10x+30)/(x-5)$

Solving this we get:

$x+(-5x+30)/(x-5)$

Quotient = x remainder = -5x+30

Now dividing, $(-5x+30)/(x-5)$ , we get

$-5+(5)/(x-5)$

quotient = -5 and remainder = 5

So, the answer is :

$x-5+(5)/(x-5)$

Therefore, option D is correct.
