19.941 would round to 20 when rounded to the nearest one.
Answer:
The radius of the circle is 93.91
Step-by-step explanation:
In order to calculate the radius of this circle we can apply the formula to find the arc length. This formula is shown below:
length = [(angle)*pi*radius]/180
Since we want to find the radius we can isolate that variable, as shown:
(angle)*pi*radius = length*180
radius = (length*180)/(angle*pi)
radius = (12*pi*180)/(23*pi) = (12*180)/23
radius = 93.91
The answer is 2,592 because when you multiply them all you get 20,736 then divide it by 8 that's what you get.
The constant of proportionality is 40 nickels/standard coins.
