Answer:
0.012
Step-by-step explanation:
Linear approximation says that,
For a cube the surface area is .
So the side is 1.0 inch in, the surface area is square inches.
In Linear approximation means you ignore the term , if is a small number, because then will be a very smalle number and that does not contribute much to the error.
So the surface area is approximately,
So here,
The error in the area is approximately,
So the error is 0.012.

2. A circle with a radius of 10cm has a circumference of...?
3. Calculate a circumference of a circle with a diameter of 13cm.
4. A circle has a diameter of 9.5cm.What is the distance around the circle?
How do you calculate the circumference of a circle?
When would you use 2nr?
When would you use nd?
Come up with your own examples(at least two) to show how to calculate the circumference of a circle.
1. The circumference of a circle is 2πr, and when we plug in 3 for r, we get 6π.
2. We'll use the same formula and plug in 10 for r, giving us 20π.
3. The formula we use in this case is πd, and when we plug in 13 for d, we get 13π.
4. Same formula from 3, we plug in 9.5 for d and get 9.5π.
5. You can calculate the circumference of a circle using 2 formulas, C=2πr (where r=radius and C=circumference) and C=πd (where d=diameter and C is circumference).
6. You use 2πr when the radius is given.
7. You use πd when the diameter is given.
8. 2 examples could be to use the 2 formulas.
