Find the total surface area of the
following cylinder:
r= 5 cm
5 cm
SA = [? ]ī cm2

Answer:

Option C. 8

Step-by-step explanation:

It is a right triangle.

let

AC = 10

BC = 6

AB = x

Using Pythagoras theorem

[tex] {ab}^{2} + {bc}^{2} = {ac}^{2} \\ {x}^{2} + {6}^{2} = {10}^{2} \\ {x}^{2} = {10}^{2} - {6}^{2} \\ {x }^{2} = 100 - 36 \\ {x}^{2} = 64 \\ x = \sqrt{64} \\ x = 8[/tex]

Answer:

25

Step-by-step explanation:

if X = 4 then you would do

4(4) + 9

since 4 x 4 is 16

add that by 9

16 + 9 = 25

so the value of 4x + 9 = 25

Answer:

[tex]\huge\boxed{\sf 995.4 in.\²}[/tex]

Step-by-step explanation:

Area of the circle:

= πr²

Where r = 21 in.

= (3.14)(21)²

= (3.14)(441)

= 1385.4 in.²

Area of triangle:

= [tex]\sf \frac{1}{2} (Base)(Height)[/tex]

Where Base = 20 in. , Height = 39 in.

= [tex]\sf \frac{1}{2} (20)(39)[/tex]

= (10)(39)

= 390 in.²

Area of the shaded region:

= Area of the circle - Area of the triangle

= 1385.4 - 390

= 995.4 in.²

Step-by-step explanation:

Answer:

36 cm

Step-by-step explanation:

The formula to find the area of a triangle is A=1/2bh where b stands for base and h for height.

So, 8 times 9 equals 72, and 72 divided by 2 is 36.

Answer:

8[tex]\sqrt{13}[/tex]

Step-by-step explanation:

Using the pythagorean theorem (Assuming the house's walls are perpindicular to the ground):

a^2+b^2=c^2

we can find that 3=a and 29=c

3^2+b^2=29^2

9+b^2=841

b^2=832

b=[tex]\sqrt{832}[/tex]

b=[tex]\sqrt{64*13}[/tex]

b=8[tex]\sqrt{13}[/tex]

That is the height that the ladder will reach

15 x 8 x 11 is greater than one yard of fabric

Step-by-step explanation:

Volume of a rectangular prism = length x width x height

15 x 8 x 11 = 1320 in^3

1 yard = 36 inches

1320 is greater than 36 inches. she does not have enough yard of fabric

Answer:

the answer is still 0.625

Step-by-step explanation:

the tenths digit is 6, the hundreds digit is 2 and the thousabds digit it 5. SInce it doesn't pass the thousands digit it's fine how it is.

The round off of 0.625 to the nearest thousandth results in 0.626.

To round 0.625 to the nearest thousandth, focus at the digit in the thousandth's place, which is the third decimal place.

In this case, the digit in the thousandth's place is 5.

Since 5 is exactly halfway between 0 and 10, we round up the previous digit, which is 2.

Therefore, rounding 0.625 to the nearest thousandth results in 0.626.

Answer:

54 cubic inches?

Step-by-step explanation:

The Surface area of bar is 7696 square mm.

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well.

We have,

The base was an equilateral triangle with a side of 16 mm and the bar was 155 mm long.

So, Surface area of Triangular Prism

= ( 16 + 16 + 16) 155 + 16  x 16

= 7440 + 256

= 7696 square mm

A F = 3.39 per sq ft. B 37.29 C 77.97

Th function is f(x) = 3.39x²

The cost of the flooring for a dining room is $410.19.

The cost of the flooring for a dining room is $6,072.31.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

Area of a square = side²

Square with side lengths = x feet.

The tile costs ​= $3.39 per square foot.

a.

The function f for the cost of the flooring.

f(x) = 3.39x²

b.

x =  11 feet

f(11) = 3.39 x 11²

f(11) = 3.39 x 121

f(11) = $410.19

c.

x = 23 feet

f(23) = 3.39 x 23²

f(23) = 3.39 x 529

f(23) = $6,072.31

Therefore,

f(x) = 3.39x²

The algebraic equation would be 3 + x - 4 = 6

Answer:

87.92 inches cubed or 87.92 in.^3

Step-by-step explanation:

The base of a cylinder is a circle, so we need to calculate the area of the circle first. The equation for the area of a circle is:

area (a) = pi * r^2 =3.14*2*2 =12.56sq.inches

again,

volume of cylinder = area of the base * the height

= 12.56 * 7

= 87.92 inches cubed or 87.92 in.^3

Step-by-step explanation:

See steps below:)

Given:

Consider the line segment YZ with endpoints Y(-3,-6) and Z(7,4).

To find:

The y-coordinate of the midpoint of line segment YZ.

Solution:

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

The endpoints of the line segment YZ are Y(-3,-6) and Z(7,4). So, the midpoint of YZ is:

[tex]Midpoint=\left(\dfrac{-3+7}{2},\dfrac{-6+4}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{4}{2},\dfrac{-2}{2}\right)[/tex]

[tex]Midpoint=\left(2,-1\right)[/tex]

Therefore, the y-coordinate of the midpoint of line segment YZ is -1.
