The circumference of an ellipse is given by an integral, though it can be approximated through some workable formulae. One such formula gives an approximate length of 72.66 ft (if the lengths given are diameters; if they are semi-axes, it gives a length of approx 145.33 ft - twice as long as the ellipse is twice as big).

Find the area of a circle 15 ft?
Area_circle = π × radius²It depends to what the 15 ft refers, if:15 ft is the radius of the circlearea = π × (15 ft)² = 225π sq ft ≈ 707 sq ft 15 ft is the diameter of the circlediameter = radius × 2 → radius = ½ diameter→ area = π × (15 ft / 2)² = 225π/4 sq ft ≈ 177 sq ft15 ft is the circumference of the circlecircumference = 2 × π × radius → radius = circumference ÷ (2π)→ area = π × (15 ft / 2π)² = 225/(4π) sq ft ≈ 17.9 sq ft
