The perimeter is 20*sqrt(2) cm = 28.2843 cm
It can have any value up to 392 square cm.
The side of the square is equal to the diameter of the circle, in this case 2a so the perimeter is 8a cm.
First you have to measure the diameter of the circle. The diameter is pi (pi is approximately 3.1415) times the diameter is the perimeter. Half the diameter is the radius and the area of a circle is pi times the radius squared. So for example, let us say that you have a circle with a diameter of 3 inches. The perimeter is then about 9.42 inches, and the area is about 7.07 square inches.
The square because its perimeter is 16 inches while the circumference of the circle is 15.708 inches.
Assuming the semicrcles make a circle that fits precisely inside the square, then the perimeter of the square is 4d, where d is the diameter of the circle (or semicircle) C Bad
To find the area of the Norman window, you need to divide the perimeter by 2 to get the width of the rectangle, which is 22.5 feet. The radius of the semicircle is half of the rectangle's width, so it's 11.25 feet. The area of the rectangle is 11.25 * 22.5 = 253.13 square feet, and the area of the semicircle is 0.5 * pi * 11.25^2 = 198.93 square feet. So, the total area of the window is 253.13 + 198.93 = 452.06 square feet.
The perimeter is 20*sqrt(2) cm = 28.2843 cm
It can have any value up to 392 square cm.
i need the answer asap plz
The perimeter of a circle is the circumference. If you mean the circle is drawn around (and touches the 4 corners of) a square, and you know the perimeter of the square, you divide the square's perimeter by 4, do pythagorean's theorem on the 2 sides (legs) to find the hypotenuse, and that hypotenuse will be the diameter of the circle. You then multiply that diameter you get by pi to get the circumference.
The largest diameter you can inscribe in a circle is a square. The square's diagonal is equal to the diameter of the circle; the length of the side of the square is therefore equal to the circle's diameter, divided by the square root of 2.
It is: pi*4^2 divided by 2 = 8/pi which is about 25 square cm
The side of the square is equal to the diameter of the circle, in this case 2a so the perimeter is 8a cm.
-- You do not need the 'square'. You only need the 'pi' and the diameter. -- The circumference of a circle is (pi) x (diameter). -- Is it really necessary to go further and point out that the length of a semicircle is 1/2 of that ?
