Nick has 30 coins in his pocket. some coins are nickels. some are dimes. the total value of all of the coins in his pocket is $1.65. let n=number of nickels . let d=number of dimes . complete each statement. the equation that represents the total number of coins is

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
