Question

What is the area of shaded section of the circle?​

Answer 1

Answer:

≈ 565.5 units²

Step-by-step explanation:

The area (A) of the shaded sector = area of circle × fraction of circle

A = πr² × $\frac{162}{360}$ ← r is the radius

   = π × 20² × $\frac{162}{360}$

   = 400π × 0.45 ≈ 565.5 units²
