Answer 1

1320mm^2

is the snsweer

Answer 2

Answer:

The area of the circular ring is 18.85 mm².

Step-by-step explanation:

Given, Outer Diameter = 38 mm

Hence, Outer Radius = 38/2 = 19 mm

Given, Inner Diameter = 32 mm

Hence, Inner Radius = 32/2 = 16 mm

Area of the outer circle = 2 × 22/7 × 19

= 119.42

Area of the inner circle = 2 × 22/7 × 16

= 100.57

Area of the circular ring = Area of the outer circle - Area of the inner circle = 119.42 - 100.57 = 18.85.
