Question

If the radius of a circle is 770 units,
what is its area (in terms of tt)? ans is 49 sq units give me step by step explanation​

Answer 1

$\red{\boxed{Answer}}$

Area of circle =

$\pi \times {r}^{2}$

So,

Here,

$\pi = \frac{22}{7}$

$r = 770 \: units$

= 22/7 × ( 770 )²

= 22/7 × 770 × 770

= 22 × 110 × 770

$\implies{\red{\boxed{1863400 \: {unit}^{2}}}}$
