radius = diameter ÷ 2
area_circle = π x radius2
= π x (20 cm ÷ 2)2
= 100π cm2
≈ 314 cm2
Using pi as 3.14 it works out that the diameter is 20 cm
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
20; the diameter of a circle is twice its radius.
Using pi as 3.14 it works out that the diameter is 20 cm
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
40 ft
The length of the diameter of a circle whose circumference is 62.8 is about 20 units (19.99). (d = c divided by Pi)
Radius = Diameter/2 so if diameter = 20 Radius = 20/2 = 10
Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle (area = pi x radius2).
