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%.
What is the area of a circle if it has a diameter of 2cm?
The area of a circle with a diameter of two cm is about 3.1416 cm.
What is The area of a circle if the diameter was s 7ft.?
The area of a circle if the diameter was s 7ft is 38.48ft
What is the Diameter of circle with a area?
the diameter is the length across the circle, the area is pie r squared r is radius, which is half of the diameter
What is the area of a circle with a diameter of 10 centimeters?
The area of a circle with a diameter of 10 centimeters is: 78.54 cm2
What is the area of a sector of a circle that has a diameter of 10 in. if the length of the arc is 10 in.?
The sector area works out as: 10/10pi times 25pi = 25 square in.

How is pi related to the circumference area of a circle?
Pi (approximately 3.14) is the ratio of the circumference of a circle to its diameter. It is calculated by circumference divided by diameter.
Area of circle with radius of 5?
A=pi times R squared If the radius is 5, the area is 25pi
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
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 s the formula for the area of a circle?
The formula for the area of a circle is πr2, or pi x radius^2 The radius of a circle is the diameter divided by two, and pi is approx. 3.1415926535
What is the diameter of a circle with a area of 37.68?
The diameter of a circle with an area of 37.68 is 6.92
What happens to the area of a circle when the diameter is halved?
It is reduced by a quarter. If you halve the you also halve the diameter The area (A) of a circle is = pi x (radius)squared. If you halve the radius and then square it then to balance the equation the area must be divided by Four.
What is the diameter of a circle with the area 49 pi?
Since the area of a circle is pi times the radius squared. The radius is 7. The diameter would be 14.
