A diameter is a line, and has no area.
A circle whose diameter is 8.5 has an area of 56.745. (rounded)
C=pi * d C=pi * 85 pi is approximately 3.141592 85 * 3.14592=267.4032
The area of a circle with a diameter of 9.4 m is: 69.4 m2
Divide the area by pi (= 3.14159 approx) to get diameter.
The diameter = sqrt (area*4/Pi) = 15.6353
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
apparently the 85 and 86 diameter is 35mm(same as the 85 tri-z 250), earlier years are smaller diameter.
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
C=pi * d C=pi * 85 pi is approximately 3.141592 85 * 3.14592=267.4032
The distance across an area measured in square miles would depend on the shape of the area. To find the distance across, you would need to know the shape's dimensions. For example, if the area is a square, you could find the distance across by finding the square root of the area. If it is a circle, you would need to calculate the diameter using the formula πr^2 = 85 square miles.
The area of a circle with a diameter of 9.4 m is: 69.4 m2
Circumference = pi*85 = 267.035 units of measurement to 3 decimal places
The diameter of a circle with an area of 37.68 is 6.92
The diameter = sqrt (area*4/Pi) = 15.6353
Divide the area by pi (= 3.14159 approx) to get diameter.
Area = (pi/4) x (Diameter)2 Diameter = 2 x sqrt(Area/pi)
The area is four times as large if the diameter doubles.The area of a circle is A = (pi)r2 or (pi)(diameter/2)2Since d is squared, it increases the area by the square of 2 if the diameter is doubled.Try calculating the area for a diameter of 2m, 4m and 8m to prove this.
The diameter is 8. The circumference is 8 pi. The area is 16 pi.
