Use the good old formula for the area of a circle:
Area = (pi) x (radius)2
You need to know the radius, right ? Well, if the circle is inscribed in a square,
you're supposed to be able to notice that the length of the side of the square
is the same as the diameter of the circle. The radius is just half of the diameter,
so you have everything you need to calculate the area.
(I'm absolutely positive that whoever assigned you the problem told you the length
of the sides of the square.)
Area of a circle = pi*radius2 The radius of the circle will be 1/2 the size of the length of a side of the square.
By using the formula: area of circle = pi*radius2
Do you know how to find the area of a circle when you know the radius ? Good! Do that. Do you know how to find the area of a square when you know the length of the side ? Good! Do that. Now you have two numbers ... the area of the circle and the area of the square. The problem wants you to find the difference of these two numbers. Do you know how to use subtraction to find the difference of two numbers ? Good! Do that.
Yes
Area of circle = 78.54 sq cm => Radius of circle = 5 cm => Diameter of circle = 10 cm => Side of square = 10cm => Area of square = 100cm2
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
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 add the area of the square with the area of the semi circle.
It means that if you take a circle and find its area, you must now find a square with the same area. We cannot square the circle.
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
Area of a circle in square meters = pi times radius squared
Area of a circle = pi*radius2 The radius of the circle will be 1/2 the size of the length of a side of the square.
To find the area of a circle inscribed in a square, you can use the formula for the area of a circle (πr^2) and the properties of a square (all sides equal). Since the diameter of the circle is equal to a side of the square, you can find the radius of the circle by halving the side length of the square. Then, plug the radius value into the area of a circle formula to find the area.
