A step-by-step explanation
This is a triangle prism, the base is a square and the four sides are equal triangles.
To find the surface area you need to first find the areas of the triangles, then the square, in the end you have to add them together.
Since we know the area of a triangle is 1/2bh we know that one if the triangle in the figure is
9*16/2=72(in^2)
there are four of these so we multiply it by 4
4*72=288(in^2 aka squared inches)
Then we need to find the area of the square. side * side=9*9=81 (in^2)
Add them together we get the surface area.
288+81=369 (in^2)
Answer:
38,200,000
Step-by-step explanation:
Put the 3 in the 8th spot to the left of the decimal point and fill in the other digits to the right of it.
38,200,000
__
The first spot immediately to the left of the decimal point has a place value of 10^0, so the location with a place value of 10^7 is the 8th spot left of the decimal point. You should be able to get the idea from the attached.
__
If you put your calculator in the appropriate display mode, it should show you the number in this form.
Answer:
Step-by-step explanation:
square prism I suppose...
Let angle HAC = A, then
cos A = 24/25 = 0.96
A = cos^-1(0.96) = 16.26
