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 :

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
