Step-by-step explanation:

Q.

If the area of the circle is 616 cm², then what is the length of the greatest chord.

Solution -

As we know,

area of circle = πr²

$> = > \pi {r}^{2} = 616 \\ \\ = > \frac{22}{7} {r}^{2} = 616 \\ \\ = > 22 {r}^{2} = 616 \times 7 \\ \\ = > 22 {r}^{2} = 4312 \\ \\ = > {r}^{2} = \frac{4312}{22} \\ \\ = > {r}^{2} = 196 \\ \\ = > r = 14cm$

Longest chord of circle = diameter (d)

=> d = 2r

=> d = 2 × 14 cm

=> d = 28 cm

Hence the longest chord of circle = 28 cm
