Question

if a string is of 20 meters find radius and area of circle​

Answer 1

$\frac{x}{y} \pi$Answer:

Step-by-step explanation:

Circumference of the circle = 20 metres.

2$\pi$r=20

∴ r=20÷2$\pi$ = $\frac{10}{\pi }$m

Area of the circle= $\pi r^{2}$=$\pi\frac{10}{\pi } * \frac{10}{\pi }$ = $\frac{100}{\pi}$ $m^{2}$.
