Ihave a homework question where i have to estimate the number of dentists in the uk. there is roughly 65,000 people in the uk and they 90% probably visit every 4-6 months.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet

the answer is a. 72. but i cant answer with less than 20 characters so here's some random text talking about it.
