The surface area of the cylinder is 1759 sq units.

The surface area is the total area covered by all the faces of a 3D object.  It is always measured in square units.

Given that a cylinder with radius 10 units and height is 18 units, we need to determine the surface area of the cylinder,

The surface area of the cylinder = 2π × radius × (height + radius)

= 2 × 3.14 × 10 × (18+10)

= 1759

Hence, the surface area of the cylinder is 1759 sq units.

Answer:

Step-by-step explanation

to find median u ned to arrange the data from ascending to descending order

Data=3,3,4,5,6,7,9,10,10

Median=N+1/2   (N means no of data)

=9+1/2

=10/2

=5 th term

=6

Mode is 3 and 10 because they repeats maximum number of time.

range=largest value-smallest value

=10-3

=7

average =sum of data/no of data

=100+91+96+93/4

=380/4

=95

therefore average is 95.

Answer:

x=1 , y= 2

Step-by-step explanation:

solving for x:

2x=3(3-x) - 4

- multiply 3 by everything in the parentheses

2x= 9-3x-4

- add 3x to both sides

5x=9-4

5x=5

- divide each side by 5( isolating x)

x=1

solving for y:

y= 3- (1)

- input our solved value for x in the orginal equation

y=2

Complete question is;

Keisha needs to make at least 32 costumes for the school play. Since she can make 4 costumes each week, Keisha plans to work on the costumes for at least 8 weeks.

Which inequality matches the problem?

A) x ≥ 8

B) x = 8

C) x ≤ 8

D) none of the above

Answer:

A: x ≥ 8

Step-by-step explanation:

Let the number of weeks be x.

She needs to make at least 32 costumes and plans to work at least 8 weeks. Since she makes 4 costumes per week, we can say that;

4x ≥ 32

I used greater than or equal to sign because she can't make less than 32 costumes.

Also, she can't use less than 8 weeks.

Thus; dividing both sides by 4, we have;

4x/4 ≥ 32/4

x ≥ 8

Answer:

[tex]C = 2[/tex] (A)

Step-by-step explanation:

We assume the constant A is different than 0

We notice that the graph of the function intercepts the x-axis when x = -0.5

we know that cos(x) = 0 when x = π/2 or x = -π/2

thus, [tex]-0.5 + C = \pi /2[/tex]    or  [tex]-0.5 + C = -\pi /2[/tex]

then [tex]C = \pi /2 + 0.5 = 2[/tex]  or [tex]C = -\pi /2 = 0.5 = -1[/tex]

so [tex]C = 2[/tex]

Answer:

12/5

Step-by-step explanation:

sqrt( x^2+49) = x+5

Square each side

(sqrt( x^2+49))^2 = (x+5)^2

x^2+49 = (x+5)(x+5)

Foil the right side

x^2+49 = x^2 +5x+5x+25

Combine like terms

x^2+49 = x^2 +10x +25

Subtract x^2 from each side

49 = 10x+25

Subtract 25 from each side

49 -25 = 10x

24 = 10x

Divide by 10

24/10 = 10x/10

12/5 =x

Check since we squared, we need to check for extraneous solutions

sqrt( (12/5)^2+49) = 12/5+5

sqrt(144/25 +1225/25) = 12/5+25/5

sqrt(1369/25) = 37/5

Answer:

8

Step-by-step explanation:

So there are two things that must be remembered.

The radius is half of the diamater. It is the distance from the side of a circle to its center.

The diamater is two times the radius. It is the distance from one side of the circle to the opposite side of the circle.

In this case, we know the radius is 4.

The radius is half of the diamamter, or the diamater is two times the radius.

This can be though of as:

2r=d

Or

1/2d=r

So lets plug 4 in for r:

2*4=d = 8=d

1/2d=4 = 2*1/2=4*2 = 1d=8

So using either of these formulas, we find d is equal to 8.

Hope this helps!

Answer: 20.25 carb per gram

Step-by-step explanation:

Given: 1 gram fat = 9 calories, 1 carb per gram =4 calories.

To convert:  9 grams of fat to carbs.

Consider  1 gram fat = 9 calories

i.e. 1 calorie = [tex]\frac19[/tex] gram fat  [divide both sides by 9]

1 carb per gram =4 calories.

= 4 x ( 1 calorie)

= [tex]4\times\frac19[/tex] gram fat

= [tex]\frac49[/tex] gram fat

Now, 1 gram fat = [tex]\frac94[/tex]carb per gram

thus,

9 grams of fat = [tex]9\times\frac94[/tex] carb per gram

=[tex]\frac{81}{4}[/tex] carb per gram

= 20.25 carb per gram

Hence, 9 grams of fat = 20.25 carb per gram
