Show me the strategy to solve 339-284

Well what I used back when I learned Hundreds subtraction was to make a table that would have the big number on top and the small number on the bottom. Now to get started I would check if a number could go into another. So I in this problem I find that 84 cant be taken away from 39 so There is a method that I learned called the "carry over" or what my teacher called it borrowing. which is Taking the number with more value and adding it like a 10 to the second number down so in 339 the first 3 would turn into 2 so 239 and then I would pass it down so 2(13)9 so then I could do 13- 8 since of there values. so that leaves me with 259 since I took it away then I would do the next 9-4 is 5 so 255 and since I took away the 84 in 284 I would get left with 200 so the final equation is 255-200=? And the final answer is 55.  Hope this helped out please comment if you need any clarifying.

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
