The area of a circle with radius 7 is πr^2. Using π ≈ 3.1416, what is the area?

The area of a circle comes from A = π r^2. With radius 7, you get r^2 = 49, so A = π × 49 = 49π. Using π ≈ 3.1416, 49 × 3.1416 = 153.9384, which rounds to 153.94. So the area is about 153.94 square units (the exact form is 49π).
