Step-by-step explanation:

3. 13×5-7+12=70

or,65-7+12=70

or,65+5=70

or,70=70

5.96/8+19-6=25

or,12+19-6=25

or,31-6=25

or,25=25

7.7×8+11+18=85

or,56+11+18=85

or,85=85

10.17-4+21-14=20

or,17+17-14=20

or,20=20

11.10×0+55+12=67

or,0+55+12=67

or,67=67

12.48/6+3×7=29

or,8+21=29

or,29=29

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.

x = 25/2304
