Find the surface area of the attached figure and round your answer to the nearest tenth, if necessary.
mariarad [96]

Answer:

S.A = 246.6 in^2

Step-by-step explanation:

The figure given above is a square pyramid, having a square base and 4 triangular faces on the sides that are of the same dimensions.

Surface area of the square pyramid is given as: B.A + \frac{1}{2}*P*L

Where,

B.A = Base Area of the pyramid = 9*9 = 81 in²

P = perimeter of the base = 4(9) = 36 in

L = slant height of pyramid = 9.2 in

Plug in the values into the given formula to find the surface area

S.A = 81 + \frac{1}{2}*36*9.2

= 81 + 18*9.2

= 81 + 165.6

S.A = 246.6 in^2

Which equation is graphed in the figure?
kenny6666 [7]

Answer: Option B.


Step-by-step explanation:

1. The equation of the line has the following form:

y=mx+b

Where m is the slope of the line and b is the y-intercept.

2. Therefore, you must solve for y to write the equation in that form:

3y-4x=\frac{7}{2}x+\frac{3}{2}y+6\\\frac{3}{2}y=\frac{15}{2}x+6\\y=\frac{30}{6}y+4\\y=5x+4

3. As you can see, the y-intercept is b=4, therefor, the equation of the option B is the equation graphed in the figure.
