The diameter of a circular swimming pool is 15 feet. Find the circumference to the nearest thousandth

C= 47.1

Step-by-step explanation:

The formula for Circumference of a circle is: C=2πr

to find the radius we find half the diameter, which would be 7.5

now for solving:

C= 2 (3.14) 7.5

C= 47.1

have a lovely night/day! Ask if you need anymore help

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

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
