Answer:
The circumference is 9 or approximately 28.26 inches.
Step-by-step explanation:
To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π=3.14).
A. the domain is all real mumber exept 6
x-6=0
x=6
you solve the denominator for x to find the domain.
B. the range is all real numbers exept 0.
to find the range you have to graph it.
obtuse angles are having value greater than 90 degree.
so ans is option A
angle DBC is greater than 90
You would estimate to 4800 and 10 then you would take 4800 divided by ten which is 480
that's the way I'd do it hope this helps
