Question

If the length of the greatest chord of the circle is 14
cm, then find the area of the circle.​

Answer 1

Answer:

144

Step-by-step explanation:

as we know longest chord of circle= diameter

r=d/2=14/2=7

A=pie(r)^2

A=22/7*(7)^2

A=22/7*49

A=144

Answer 2

Answer:

$154 { \: cm}^{2}$

Step-by-step explanation:

we know that the greatest chord is the diameter. Hence dia is 14 cm and radius is 7 cm

Area is

$\pi {r}^{2} = \frac{22 \times 7 \times 7}{7} = 154 \: {cm}^{2}$
