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 =
Here, r = Radius of the circle
θ = Angle at the center formed by the arc
Substituting values in the given formula,
Area =
=
= 19.547
≈ 19.55 square km
Therefore, area of the sector will be 19.55 square km.
