A circle with a radius of 9 cm has an area of 254.47 square cm
circumference = pi*18 cm area = pi*92 square cm
Circle area = (pi)r2 = 254r2 = 254/pir = √254/pi ≈ 92r = diameter = 2(9) = 18 cm
A circle with a diameter of 8.5 cm has an area of 56.75 square cm
The area of a circle that has diameter of 3 cm is: 7.069 cm2
A circle with a radius of 9 cm has an area of 254.47 square cm
Using 3.14 as Pi the area of circle is: 254.34
circumference = pi*18 cm area = pi*92 square cm
Circle area = (pi)r2 = 254r2 = 254/pir = √254/pi ≈ 92r = diameter = 2(9) = 18 cm
The area of a circle with a diameter of two cm is about 3.1416 cm.
