What percentage of the square is occupied by the circle when it is inscribed in a square and tangent at all four sides?
Say the radius of the circle is x. This makes the area of the circle pi x2. Since the length of the square's sides is the diameter of the circle, 2x, its area is 2x * 2x = 4x2. The percentage occupied by the circle is the area of the circle divided by the area of the square times 100 pi/4 x 100; pi/4 x 100 = 100pi/4 = 25pi = 78.6%.

How do you find out the radious of a circle?
The radius of a circle is the distance from the centre of the circle to a point on the circumference of the circle. If it is a drawing and the circle is to scale the radius can be measured with a ruler. If not, the radius can be calculated if the diameter, circumference or area of the circle is known. the radius is equal to: - the diameter divided by 2 - the circumference divided by 2pi(approx. 6.284) - the square root of the area divided pi (divide by pi first, then take the square root)
What is the area of a sector of a circle which has a diameter of 10 inches if the length of the arc is 10 inches?
diameter d = 10 in radius r = 5 in arc length s = 10 in C = pi d = pi x 10 in = 10pi in s/C = 10 in/10pi in = 1/pi A circle = pi r2 = pi(5 in)2 = 25pi in2 A sector/A circle = 1/pi (cross multiply) pi A sector = 25pi in2 (divide both sides by pi) A sector = 25 in2
