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.
