Area = (pi) x (radius)2 = (pi) x (10)2 = 314.16 (rounded)
If the diameter of a circle 20 cm is tripled the area will increase from 314.2 cm2 to 2,827 cm2
Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle (area = pi x radius2).
314 ft2
Area of circle: pi*20^2 = 400*pi square units
(100 pi) square inches is.
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?
If the diameter of a circle 20 cm is tripled the area will increase from 314.2 cm2 to 2,827 cm2
Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle (area = pi x radius2).
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
The area is the same as that of a big 20 ft circle. Assuming the 20 ft refers to the diameter of the circle, its area is 314.159 sq ft (to 3 dp)
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
