Like in real life problems?
if yes then when conducting a survey, when grading quizzes/assignments, etc
The tenths place is right after the decimal point. So, 3160.9903 can be 3160.9.
Let Surface Area A, a the base edge and h the height:
A = a²+2a√(a²/4+h²)
h=?
pythagorean theorem:
h²=c²-a²
h=√(c²-a²)
h=√(8²-(.7/2)²)= 8
plug it in the above equation A= 11.7ft²
So A is correct
The 3 it is the one the bottom left corner
