Didier whants to buy a bike that cost $125 he aredy has saved $65 he earns $12 each hour working a a life garud abd saves all of it for the bike how many hours dose dider need to work in order to have money to buy the bike

5 Hours of work.

Step-by-step explanation:

Subtract 125 by 65 and we get 60. Then divide that 60 by how much he gets paid an hour ($12), and you get 5 hours of work until he can buy the bike.

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.
