Question

si la longitud circular es 100 cuál sería el área y el radio ? ​

Answer 1

$l = 100m \\ l = \pi \times d \\ d = \frac{l}{\pi} \\ \\ d = \frac{100m}{3.1416} \\ \\ d = 31.83m \\ \\ a = \frac{\pi \times {d}^{2} }{4} \\ \\ a = \frac{3.1416 \times ( {31.83m)}^{2} }{4} \\ \\ a = \frac{3.1416 \times 1013.1489 {m}^{2} }{4} \\ \\ a = \frac{3182.91 {m}^{2} }{4} \\ \\ a = 795.73 {m}^{2}$
