To find area of a circle, the formula is πr2 where π is pi. Half of the diameter is the radius (r) so you divide 18 by 2 to get the radius (9). then, you square it (multiply it by itself) giving you 81. You then multiply this by pi to get the area. The exact answer is 81π, with a good approximation of: 254.46900494077325231547411404563973361997072134938357149897

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.
