An architect is making a plan for a new circular playground. If the playground has a diameter of 60 feet, how much fencing needs to go up to keep the kids in the circle?

188.5 ft

Step-by-step explanation:

The circumference of a circle of diameter d is C = dπ.

Here, the circumference = length of fending needed = π(60 ft) = 60π ft, or approximately 188.5 ft

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
