Answer:
Part 1) The diameter is
Part 2) The radius is
Part 3) The length of an arc is equal to
Step-by-step explanation:
Part 1) Find the diameter
we know that the circumference of a circle is equal to
where
D is the diameter
we have
assume
substitute and solve for D
Part 2) Find the radius
we know that
The radius is half the diameter
so
substitute
Part 3) Find the length of an arc of 190 degrees
we know that
The circumference of the circle subtends a central angle of 360 degrees
so
using proportion
