Question

Area of circle radius is 5 numerically what percent of its circumference

Answer 1

Step-by-step explanation:

Radius of the circle r = 5 units

$Circumference \: of \: the \: circle = 2\pi \: r \\ = 2 \times \pi \times 5 \\ = 10\pi \\ numerical \% \: of \: radius \: to \\ \: its \: circumference \: = \frac{radius}{circumference} \times 100 \\ = \frac{5}{10 \pi} \times 100 \\ = \frac{50}{ \pi} \\ = \frac{50}{ \frac{22}{7} } \\ = \frac{50 \times 7}{22} \\ = \frac{25 \times 7}{11} \\ = \frac{175}{11} \\ = 15.9090\% \approx \: 15.91\% \:$
