What is the distance from L to M?
A. 10 units
B. 14 units
C. 100 units
D. 2 units

Step-by-step explanation:

First, you'd get the area of the circle, then multiply it by two (there's two ends to a cylinder)

so (pi)(R^2)

If 8 is the diameter, then 4 is the radius (r=1/2d)

3.14{pi}*16{4 squared}+=50.27

(50.27*2)= 100.54

Now, we need to find the area of the side of the cylinder. We have the given height of 16.8, and now we need to find the length. In order to do that, we must find the perimeter/diameter of the circle with the formula of Pi*Diameter.

if the diameter of the circle is 8, then 3.14*8=25.12.

25.12*16.8=422.016

now we need to add the area of the circles to get total surface area.

100.54+422.016= 522.556cm^2

I hope this helps!

The surface area of the given cylinder is 522.496 cm².

A cylinder is a three dimensional figure which is formed by two parallel circular bases joined by a curved surface.

Center of the two bases is joined by a line called the axis of the cylinder.

Total surface area of cylinder can be found by the total of area of circular bases and the area of curved surface.

Total surface area = Area of Circular bases + Area of curved surface

                               = 2π r² + 2π r h

where r is the radius of the circular base and h is the height of the cylinder. π is the pi constant with value 3.14

Here, r = 8/2 = 4 cm and h = 16.8 cm

Total surface area = 2πr (r + h)

                               = 2π × 4 (4 + 16.8)

                               = 8π × 20.8

                               = 166.4π

                               = 166.4 × 3.14

                               = 522.496

Hence the surface area of the cylinder is 522.496 cm².

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use Pythagorean's theorem. If the sides satisfies Pythagorean theorem, then, they form a right angled triangle.

The longest side is hypotenuse.

Hypotenuse² = base² + altitude²

10²  = 6² +8²

100 = 36 + 64

100 = 100

So, 6cm, 8cm, 10 cm makes an right angles triangle.

Answer:

(-2,4)

Step-by-step explanation:

When reflecting a point across y=x, the x-coordinate and y-coordinate switch places.

=========================================================

Explanation:

Point Q is located at (0,w). We see that x = 0 and y = w.

So we'll replace x with 0 and y with w. Then we solve for w.

2x+3y = -12

2(0)+3(w) = -12

0+3w = -12

3w = -12

3w/3 = -12/3

w = -4

In the second to last step, I divided both sides by 3 to undo the multiplication of 3. Saying 3w means "3 times w".

Side note: The point Q is the y intercept as this is the location where the diagonal line 2x+3y=-12 crosses the vertical y axis.

Answer:

x = -17/2

Step-by-step explanation:

2(x+13)=9

2x+26=9 (multiplying 2 with both the numbers)

2x=9-26 (shifting 26 on the other side of the equation changes its sign)

2x=-17

x=-17/2 (2 is in multiplication form, so shifting on the other size changes it into division)

Answer:

2 x x + 2x13=8

or,2x+26=9

or,2x=9-26

or,2x= -17

or,x= -17/2

so, x= -8.5

Answer:

x=7

Step-by-step explanation:

You know that the 17x+11 and 19x-3 are equal because they are corresponding angles. Then, you would solve it like an algebraic equation:

17x+11 = 19x-3

Move all the like terms onto one side.

14=2x

It would be easier to look at if moved the x onto the left so it would look like this:

2x = 14.

Then divide by 2 and your answer should be 7.

Answer:

75

Step-by-step explanation:

When you have 100% of something, it's all of that one thing, right? So if you were to turn 100% into a decimal, it would be 1. This means you can divide any percentage by 100 to turn it into a decimal. So, 30%=.3. When you multiply something by 2, you get two of that thing, right? And just the same, when you multiply something by half, you get half of that thing. This means you can multiply 250 by .3 to get .3 of it, or, 30%.

250*.3=75
