The area of a circle with a diameter of 9.4 m is: 69.4 m2
A diameter is a line, and has no area.A circle whose diameter is 8.5 has an area of 56.745. (rounded)
Divide the area by pi (= 3.14159 approx) to get diameter.
The diameter = sqrt (area*4/Pi) = 15.6353
The diameter is 8. The circumference is 8 pi. The area is 16 pi.
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
The area of a circle with a diameter of 9.4 m is: 69.4 m2
A diameter is a line, and has no area.A circle whose diameter is 8.5 has an area of 56.745. (rounded)
The diameter of a circle with an area of 37.68 is 6.92
Divide the area by pi (= 3.14159 approx) to get diameter.
The diameter = sqrt (area*4/Pi) = 15.6353
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
To convert diameter to area , you will need to divide the diameter by two so as to get the radius. The result you get, square it and them multiply it by 3.14 to find the area.
If Area of a circle = (2)(pi)(r), and diameter = 2r, then: diameter = 2r = Area of circle / pi, where pi = 3.14
