area of circle diameter 6 use 3.14 for pi
The radius of the circle is half of the diameter, so the radius is 6/2 = 3.
The area of a circle is calculated using the formula A = πr^2, where A is the area, π (pi) is approximately 3.14, and r is the radius.
Substitute the values into the formula:
A = 3.14 * 3^2
A = 3.14 * 9
A = 28.26
Therefore, the area of a circle with a diameter of 6 is 28.26 square units.
