Answer:
C. 726 in^2.
Step-by-step explanation:
Each face has area 11^2 = 121 in^2 ( because each face is a square).
There are 6 faces so the total surface area = 6 * 121
= 726 in^2.

Step-by-step explanation:
Percent error = |actual − theoretical| / actual × 100%
|42 − 30| / 42 × 100% = 28.6%
Answer:
C = 3.14... x d
Step-by-step explanation:
To calculate the circumference do pie times the diameter of the circle
Substituting z = 5 into the first equation:
2x - y + 5 = -4
y = 2x + 9
Substituting y and z into the third equation
-2x + 3(2x + 9) - 5 = -10
4x + 27 = -5
x = -8
y = 2(-8) + 9 = 7
z = 5
