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
The diameter = sqrt (area*4/Pi) = 15.6353
Divide the area by pi (= 3.14159 approx) to get diameter.
The diameter is 8. The circumference is 8 pi. The area is 16 pi.
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 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.
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
