WebThe radius is half of the diameter. It starts from a point on the circle, and ends at the center of the circle. ... Anyway, back to the problem. If we say the circumference is 1600 pi, and this is equal to pi times the diameter, we can just divide both sides by pi to get the diameter, which is going to be 1600. The circumference is 1600 pi ... WebDec 16, 2024 · To find the square footage of any circle: Multiply π (pi) by the diameter square: π (16 ft)² = 804.25 ft². Divide that result by four: 804.25 ft²/4 = 201.06 ft². That's the square footage of your circle. We use the same steps when calculating the SF of a circle formula SF = πd²/4. Luis Hoyos.
