A circle with a diameter of 18 cm has a radius of 9 cm, since the radius is half the diameter. The circumference of the circle can be calculated using the formula (C = \pi d), which gives approximately 56.55 cm. The area can be found using the formula (A = \pi r^2), resulting in approximately 254.47 cm². This circle represents a two-dimensional shape where all points are equidistant from the center.

What is the diameter of a circle with an area of 254 cm?
To find the diameter of a circle with an area of 254 cm², you first need to calculate the radius. The formula for the area of a circle is A = πr², where A is the area and r is the radius. So, 254 = πr². Solving for r gives you r ≈ √(254/π) ≈ 9 cm. The diameter of a circle is twice the radius, so the diameter of this circle is approximately 18 cm.
