Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle (area = pi x radius2).
The area of a circle is (pi) times (the radius)2. The radius of the given circle is 1/2 of the diameter = 20m. Area = (pi) times (20)2 = 400(pi) = 1,256.64 square meters(rounded)
If the diameter of a circle 20 cm is tripled the area will increase from 314.2 cm2 to 2,827 cm2
314 ft2
Area of circle: pi*20^2 = 400*pi square units
Using 3.14 as Pi the area of circle is: 1256.0
Diameter is 20 meters, hence radius is 10 meters. Area of circle = pi * r * r = 3.1415 * 10 * 10 = 3.1415 * 100 = 314.15 square meters
If the circumference of a circle is 62.8 meters the diameter is: 20 meters.
The area of a circle with a diameter of 20 cm is: 314.2 cm2
If area of circle is equaled to 100pi what is the radius?
If the area of a circle is 20 square inches the diameter is: 5.046 inches.
The area of a circle is (pi) times (the radius)2. The radius of the given circle is 1/2 of the diameter = 20m. Area = (pi) times (20)2 = 400(pi) = 1,256.64 square meters(rounded)
A cylinder with a height of 20 meters and a diameter of 10 meters has a surface area of 785.4m2
If the diameter of a circle 20 cm is tripled the area will increase from 314.2 cm2 to 2,827 cm2
314 ft2
314 ft2
The diameter of the circle works out as 20 units to the nearest whole number
Area of circle: pi*20^2 = 400*pi square units
