The diameter is 93.
the diameter is the length across the circle, the area is pie r squared r is radius, which is half of the diameter
The area of a circle is A = pi times diameter² / 4. Given diameter d = 10 inches. Area A = 78.5398 inches².
Hold it right there. That's not possible. Something's gotta give.The area of a circle = pi R2 = pi (half the diameter)2If the circle has a diameter of 16, then its area is 201.1(rounded).If it has an area of 64, then its diameter is 9.03(rounded).If it has a diameter of 16 and an area of 64, then it's not a circle.
The area of a circle with a diameter of two cm is about 3.1416 cm.
