A circle with a diameter of 8.5 cm has an area of 56.75 square cm
Area can be expressed by the formula A=(Pi)r2, where A is the area and r is the radius.To find the radius of the circle, divide the diameter by 2.14 cm/2 = 7 cmA = (3.14159)(72)= 153.938 cm2Therefore, the area of a circle with a diameter of 14 cm is approximately 153.9 cm2.
The area of circle that has a diameter of 6.5 cm is: 33.18 cm2
The area of a circle that has diameter of 3 cm is: 7.069 cm2
For a circle with a diameter of 100 cm, the area is ≈ 9,503.32 cm2
