If the circumference is 12 pi what is the diameter

Answers

Answer 1

Answer: So,

The formula for the circumference of a circle:
$C = 2 \pi r\ or\ C = \pi D (diameter)$

We can now substitute the given values and solve for D.
$12 \pi = \pi D$

Divide both sides by pi.
$12 = D$

The diameter of the circle is 12 units.

Answer 2

Answer: well, since the equation for circumference is $2 \pi r^(2)$ and the diameter is double the radius, the diameter will end up being about 3.82

What does b−2≥−1 equal ????

Answers

b - 2 > -1

This is an inequality equation. It is not equal to a specific number. There are a lot of numbers that can be considered as long as it makes the inequality equation TRUE.

b - 2 > -1
+ 2 + 2
b > 1

b is a number that is at least 1 or greater than 1.

b = 1

1 - 2 > -1
- 1 > -1 True. Had the sign been only > and not >, 1 would not be a value of b.

b = 2
2 - 2 > -1
0 > -1 True.

b-2≥-1
b≥-1 + 2
b ≥1

so b ≥1
