Circumference and area of circles are related to the radius, which is a critical component.
A radius of 7 units corresponds to a circumference of 44 units and an area of 154 square units.
When the radius is 14 units, the circumference is 88 units, and the area is 616 square units.
A radius of 21 units results in a circumference of 132 units and an area of 1386 square units.
As the radius increases to 28 units, the circumference becomes 176 units, and the area becomes 2464 square units.
With a radius of 35 units, the circumference is 220 units, and the area is 3850 square units.
A radius of 42 units corresponds to a circumference of 264 units and an area of 5544 square units.
The largest radius listed, 49 units, results in a circumference of 308 units and an area of 7546 square units.
