A clock is in the shape of a circle with radius r. The area A is given by the formula A=πr^2. Solve the formula for r. Then approximate the radius of the clock that has an area of 200 square inches.

Please help me and show me how to do it!!

7.97 inches.

Step-by-step explanation:

Given the area of the clock is 200  sq inches.

#The clock is circular and its area is calculated using the formula:

Where r is the clock's radius and is a constant()

#We substitute for and the given area(200 sq inches) in the area function to solve for r:

Hence, the clock's radius is 7.97 inches.

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
