A circle is inscribed in a square. The area of the square is 100 square units. What is the area of the circle?
571
1070
2571
1001
100

It may not be one of those choices, but I got 25π

Step-by-step explanation:

The side lengths of the square have to be 10, since 10x10=100. The circle's radius then has to be 5. πr^2 is the area of a circle, so plug in r for 5. π5^2 equals 25π.

Unless the size of the circle is smaller or bigger, I didn't get those answers..

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

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
