can someone explain the meaning of surface area and give me an example of it is

Answers

Answer 1

Answer:

The surface area of a solid object is a measure of the total area that the surface of the object occupies. ... Their work led to the development of geometric measure theory, which studies various notions of surface area for irregular objects of any dimension. An important example is the Minkowski content of a surface.

Determine the center and radius of the following circle equation: x^2+y^2-8x+6y-75=0 x 2 +y 2 −8x+6y−75=0 Center: \big(( , \big)) Radius:

Answers

Answer:

Compare x^2 +y^2-8x-6y=75 with the general circle equation x^2+y^2 -2ax-2by+c=0

-2a =-8 And -2b=-6

a=4 b=3

c=-75

To find the radius use the equation

r^2=a^2+b^2-c

r^2=4^2+ 3^2-(-75)

r^2=25+75=100

r=10(radius is always positive)

Hence the center is (4,3) and radius 10

Step-by-step explanation:

because 14 and 2 go into the table of 2

you first find out what number in table 2 go into 14 in this case 7 times 2 and then you find what number in the time table 2 give you 2 so it's 2 times 1. because it's c squared you can't not put both c inside due that would not be factorizing due that it's common and it does not have to be common.

so the answer will be 2c(7c+1)

Answer:

x = 1z = 11

Step-by-step explanation:

If we assume that the segment marked (2x+1) is a midsegment, then it is half the length of the parallel base:

  2(2x+1) = 8x-2

  4x +2 = 8x -2 . . . . eliminate parentheses

  4 = 4x . . . . . . . . . . add 2-4x to both sides

  1 = x . . . . . . . divide by 4

__

The above assumption makes the two segments marked with z-expressions be the same length:

  3z = z +22

  2z = 22 . . . . . .  subtract z

  z = 11 . . . . . . . . . divide by 2

The values of X and Z are 1 and 11, respectively.

A company is desinging a square prism. Its height is 3 yarss longer than a side of its base. The volume of the prism must be 20 cubic yards. Write a representative function for the volune of the solid..

Answers

Answer:

[tex]a^{2} (a+3) = 20\\OR\\a^3 +3a^2 -20 = 0[/tex]

Step-by-step explanation:

Given that:

There is a square prism which has height equal to 3 yards longer than that of the base of the prism.

Let the base of prism = [tex]a[/tex] units

As per question statement:

Height, [tex]h = (a+3)[/tex] units

Volume of the prism = 20 cubic yards

Now, we have to find a representative function that will represent the volume of the solid.

First of all, let us have a look at the formula for volume of a prism.

[tex]V = B\times h[/tex]

Where, [tex]B[/tex] is the area of base and

[tex]h[/tex] is the height of prism.

And the base is a square, whose area will be represented as:

[tex]B = Side \times Side[/tex]

Now, putting the values in the formula for Volume:

[tex]V = a^2(a+3) = 20\\OR\\a^3+3a - 20 =0[/tex]

Triangle Deff is shown below. 110°, e, d, f, 135°​

Answers

Answer:

Step-by-step explanation:

a° + 110° = 180° [Linear pair of angles]

a = 180° - 110°

a = 70°

b° + 135° = 180° [Linear pair of angles]

b = 180° - 135°

b = 45°

a + b + c = 180° [Triangle sum theorem]

45° + 70° + c = 180°

c = 180° - 115°

c = 65°

Therefore, a triangle similar to DEF will have an angle that measures 45 degrees, an angle that measures 70 degrees and an angle that measures 65 degrees.
