Pi-R-Squared.

pi*R^2

That's the formula for area of a circle, where R=radius.

For R=7 the formula gives 49pi. Some calculators have pi buttons, but estimating pi=3.14 is often close enough for real-world application.

49*3.14 = almost 154 square feet.

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
