Answer:
5.6 units
Step-by-step explanation:

Given that the area of the circle is 31.36π,
31.36π= πr²
Divide both sides by π:
31.36= r²
r²= 31.36
Square root both sides:

r= 5.6 units
Answer:
x = 2.5
Step-by-step explanation:
Hypotenuse ² = opposite ² + adjacent ²
(x + 4)² = x² + 6²
x² + 8x + 16 = x ² + 6²
x² + 8x + 16 - x² = 6²
8x + 16 = 36
8x = 36 - 16
8x = 20
x = 20/8
x = 2.5
Answer:
c sorry if its wrong
Step-by-step explanation:
From an absolute value inequality, we have that:
- The minimum diameter is 6.46 mm.
- The maximum diameter is 6.54 mm.
- The absolute value measures the <u>distance of a point or a function to the origin</u>.
- One example of inequality is:

Which has solution:

In this problem:
- Bolts with a diameter of 6.5 mm, with a tolerance of 0.04 mm, thus the <u>absolute value of the difference of the diameter D and 6.5 has to be of at most 0.04</u>, that is:

Applying the solution:






- The minimum diameter is 6.46 mm.
- The maximum diameter is 6.54 mm.
