To find the diameter, we can derive the radius from the area. Then we can double it to find the diameter. Area = pi * r2 654 cm2 = pi * r2 654 / pi = r2 208.174665564 = r2 In order to isolate r, we have to take the square root of both sides. Another way to do this is to apply an exponent of 1/2. This cancels out on the right side, leaving a single r. 208.174665564(1/2) = (r2)(1/2) r = 14.428 cm diameter = 2*r = 28.8565

What is the area of a circle that had a diameter of 12 centimeters?
113.1 square centimeters.
The area of a circle is 12.56 square centimeters. What is the circle's diameter?
Its diameter is about 4 cm rounded
What is the area of a circle with a diameter of 10 centimeters?
The area of a circle with a diameter of 10 centimeters is: 78.54 cm2
What is the area of a circular region whose diameter is 12 centimeters?
the area of a circle is pi times the radius squared. The diameter is 12, so the radius is 6 (half of the diameter). Therefore, the area is pi times 6 squared, which is 36 pi square centimeters. Also, if you want the answer in decimal, it's 113.09733552923255658465516179806 square centimeters.
