Answer:

C = 37.68 (using 3.14)

if you use a calculator you would get 37.69911184

Step-by-step explanation:

C = [tex]2\pi r[/tex]

C = 2(3.14)r

C = 6.28(6)

C = 37.68 (aprox)

Answer:

Step-by-step explanation:

slope is equal to "rise over run"

or = rise / run.

if you mean by  

a rise and a run of 4;

rise = 4 & run = 4,

then the slope is 4 / 4 = 1.

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:

A, D,F are triangle sides

Given:

Number of tomatoes Sheldon picks = [tex]4\dfrac{4}{10}[/tex] kg

Rotten tomatoes = 1.5 kg

To find:

How many kilograms of tomatoes were not rotten?

Solution:

Number of tomatoes Sheldon picks = [tex]4\dfrac{4}{10}[/tex] kg

                                                            = [tex]\dfrac{4(10)+4}{10}[/tex] kg

                                                            = [tex]\dfrac{40+4}{10}[/tex] kg

                                                            = [tex]\dfrac{44}{10}[/tex] kg

                                                            = [tex]4.4[/tex] kg

Rotten tomatoes = 1.5 kg

Remaining tomatoes which are not rotten is

Required tomatoes = Tomatoes Sheldon picks - Rotten tomatoes

                                = [tex]4.4-1.5[/tex]

                                = [tex]2.9[/tex] kg

Therefore, the tomatoes which were not rotten is 2.9 kg.

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

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:

x=8

Step-by-step explanation:

Angle S and R are remote interior angles which means that they would add up to equal angle RQK.

78+5x-1=15x-3

Combine like terms

77+5x=15x-3

Add 3 on both sides

80+5x=15x

Subtract 5x on both sides

80=10x

Divide 10 on both sides

x=8

Step-by-step explanation: not sure about the last one.

Answer:

y = 1/2x + 1

In order to evaluate a slope that is perpendicular to the given equation, you need to find the opposite reciprocal of the original slope. This means you take the original slope, flip the numerator and the denominator, and change the sign in front.

-2 ⇒ 1/2

Next, we need to substitute the information given into the point-slope formula.

The point-slope formula is:

y - y₁ = m(x - x₁)

y - 1 = 1/2(x - 0)

y - 1 = 1/2x

y = 1/2x + 1

Therefore, the line perpendicular to y = -2x + 2 is y = 1/2x + 1.
