Asquare has a side that measures 2.75 units. what is the area of a circle with a circumference that equals the perimeter of the square?

9.63 square units

Step-by-step explanation:

It is given that, a square has a side that measures 2.75 units.

To find the perimeter of square

Perimeter = 4 * side

 = 4 * 2.75

 = 11 units

To find the radius of circle with circumference 11 units

Circumference = 2πr

2πr = 11

r = 11/2π

To find the area of circle

Area of circle = πr²

= π(11/2π)²

= (π * 11 * 11/4π²)

= 121/4π

= 121/(4 * 3.14)

= 9.63 square units

9.62 square units

Step-by-step explanation:

Given : The side of square =  2.75 units.

Then the perimeter of the square will be :-

Now, let the circumference of the circle be :_

Also, the circumference of circle is given by :-

Area of circle :

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
