The diameter of the dart board is 36 centimeter. what is the approximate circumference

36/2= r (r=18)

c=2πr

2x3.14x18=113.04        2xπ= 6.28

Step-by-step explanation:

113.04 centimeters

hope this helps!

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
