Answer:

Step-by-step explanation:
The equation of a circle with center (a,b) and radius r, is

From the question, the center of the circle is located at (-6,2) and the radius is

We substitute the center and radius to get:

Simplify to obtain:

Answer:
219.8
Step-by-step explanation:
you multiply 70 and 3.14 and get 219.8
An inequality can be formed by simply translating the problem statement to numerical expressions.
From the problem we know that

added with

hours should be equal or greater than

(helpful insight from the keyword "at least"). Therefore, it's inequality would look like:

(>= is used instead of ≥ for constraints in formatting)
The inequality above best models the situation.
Um 4.2 maybe since -4.2 and 4.2 or on the opposite scale
