Find the surface area plz

Mathematics

Hi again! ;)

If we want to find the surface area of a cube, we need to find the area of one surface first, and then multiply that by 9, since there are 9 sides/surfaces on a cube.

Since each side of a square is the same, we first find the area of one surface:

9 × 9 = 81

Then, to find the surface area, we multiply 81 by 6:

81 × 6 = 486

The surface area is
486 \:  {in}^{2}

Can someone answer each step of this correctly?
Burka [1]

About Slope - Intercept Form:

  • y = mx + b
  • m is the slope
  • b is the y-intercept

About Standard Form:

  • Ax + By = C
  • A & B & C are integers
  • A & B are both non-zero
  • This form is good to use when wanting to find the x & y intercepts of a line

About Point - Slope Form:

  • Y - Y1 = m (x -X1)
  • Y1 & X1 is a point on the line
  • The form allows you to identify the slope & the point on the line

Other Info:

  • Remember, y comes before the x  
  • An ordered pair from your problem: (-3,1), -3 is x & 1 is y & x is before the y
  • An ordered pair from your problem: (3,5), 3 is x & 5 is y & x is before the y
  • For the graph, the vertical line is y
  • For the graph, the horizontal line is x

Hope this information helps!!! :)

A figure is created by using four semicircles and a rectangle. which is closest to the area of the figure? ​
Katena32 [7]

Step-by-step explanation:

area of rrctangle:

12×8= 96cm²

now if rectangle dissapears and then we "glue" what's left, we gonna get two circles

area of circle which gas diameter of 12cm( so radius will be 6cm)will be

πr²=36π≈113.04

another circles radius is 4cm,so area is:

16π≈50.25

sum of all areas: S≈96+113.04+50.25≈259.28cm2
