What is the circumference when the area is 5.3?

Answer 1

To find the circumference of a circle given its area, we can use the formulas for area (A = \pi r^2) and circumference (C = 2\pi r). First, we solve for the radius (r) using the area: (r = \sqrt{\frac{A}{\pi}} = \sqrt{\frac{5.3}{\pi}} \approx 1.303). Then, we calculate the circumference: (C = 2\pi r \approx 2\pi \times 1.303 \approx 8.179). Thus, the circumference is approximately 8.18.
