when you have to measure out the width of the circle, example pipes
EG:And many more real life day to day things
That would certainly do it.
all you do is find the area of the circle... if you mean find the squares area, find the area of the circle, and then the square's area and subtract the squares area to the circles area
You find the area of the whole square first. Then you find the area of the circle inside of it And then subtract the area of the circle from the area of the square and then you get the shaded area of the square

To find the area of the circle pi*radius*squared and subtract the area of the figure inside
The area of a circle is given by the formula A=pi x r2 Where A is the area of the circle, pi is a constant approximately equal to 3.1415, and r is the radius of the circle. So, to find the area of a circle with a radius of 5cm you would first square the radius -- 25 cm2. Then times by pi. So the answer would be 25pi cm2.
Well, what you do is you would find the circumference, or the distance around the circle.
Area of a circle = pi*radius2
Find the area of the circle and divide by 4.
First find the area of the larger circle and then subtract the area of the smaller circle. Area=(pi x radiuslarger)-( pi x radiussmaller)
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
Area of a circle = pi*radius2
