Answer 1

Answer:

19.55 square km

Step-by-step explanation:

Area of a circle is given by A = πr²

And area of it's sector is given by the formula,

A = $\frac{\theta}{360}\times (\pi r^2)$

Here, r = Radius of the circle

θ = Angle at the center formed by the arc

Substituting values in the given formula,

Area = $\frac{35}{360}\times \pi (8)^2$

        = $\frac{2240\pi}{360}$

        = 19.547

        ≈ 19.55 square km

Therefore, area of the sector will be 19.55 square km.
