Answer 1

Answer:

after that subtract the inner area from oute area and u will get the area of the shaded portion

Answer 2

Step-by-step explanation:

First.

side of square = 3.2mm

Diameter of circle= 1.6mm

so, radius = 1.6/2 = 0.8mm

Area of shaded portion = Area of square — Area of Circle.

Area of square = (side)²

= (3.2)² = 10.24 sq mm

Area of circle = πr²

= 3.14 × 0.8 × 0.8 = 3.14 × 0.64

= 2.0096 sq mm

Area of shaded Portion = (10.24 — 2.0096) sq mm

= 8.23 sq mm Answer
