What is the area of a circle with radius 7?

Area of a circle is found using A = π r^2. With a radius of 7, the area becomes π × 7^2 = π × 49 = 49π. That’s why the correct choice shows 49π—the area must include π and reflect the radius squared, which is 49. The other options don’t fit: 14π would come from a radius whose square is 14 (radius √14), 21π from radius √21, and 49 without π isn’t the actual area since the circle area always includes the π factor.
