Question

The area of a circle is 50.24 square millimetres. What is the circle's diameter? Use 3.14 for ​pi

Answer 1

$\pi {r}^{2} = 50.24$

$3.14 {r}^{2} = 50.24$

${r}^{2} = \frac{50.24}{3.14}$

${r}^{2} = 16$

$r = \sqrt{16}$

$as \: we \: know \: that \: r \: cant \: be \: negative$

$therefore \: ,$

$\implies$$r = 4$
