How to Calculate the Area from a Circle’s Circumference
The relationship between a circle’s circumference and area is rooted in core mathematical formulas. The circumference (C) of a circle is calculated by (C = 2\pi r), where (r) is the radius. To find the area (A), use (A = \pi r^2). By rearranging the circumference formula, (r = \frac{C}{2\pi}), plugging into the area gives:
[ A = \pi \left(\frac{C}{2\pi}\right)^2 = \frac{C^2}{4\pi} ]
Plugging in (C = 31.4) meters, the area simplifies to approximately 78.5
