The area of a circle with a diameter of 20 cm is: 314.2 cm2
The diameter of the circle works out as 20 units to the nearest whole number
A circle with a radius of 10 cm has an area of 314.16 square cm
Area of circle: pi*10^2 = 100*pi square inches
Area of the circle: pi*20*20 = 400*pi square cm
Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle (area = pi x radius2).
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 the area of a circle is 20 square inches the diameter is: 5.046 inches.
If area of circle is equaled to 100pi what is the radius?
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
The diameter of the circle works out as 20 units to the nearest whole number
