The Diameter of the circle =7m
Answer:
Function - Yes
Domain - [-3,0,3,4]
Range - [1,2,2,5]
Step-by-step explanation:
In a function, x-values cannot repeat and in this relation, x's do not repeat, therefore it is a function. The domain is the x-values on the graph from least to greatest; so to find the domain, simply take the first value of each coordinate and order them from least to greatest. Then, the range is the y-values, so to find the range take the second value from each coordinate and order them from least to greatest.

Answer:
The arc length of the semicircle is
or 
Step-by-step explanation:
The complete question in the attached figure
we know that
The circumference of a semicircle is given by the formula

where
D is the diameter of the semicircle
we have

substitute

----> exact value
Assume

----> approximate value
therefore
The arc length of the semicircle is
or
