Answer 1

Answer:

Step-by-step explanation:

Given :-

Diameter of outer circle = 20cm

Radius of inner circle = 6cm

SOLUTION :-

Radius of outer circle = 20/2 = 10cm

We know,

Area of circle =  

Shaded region = Area of outer - Area of inner circle/2

Shaded region→ 22/7 × 10 × 10 - 22/7 × 6 × 6/2

Shaded region→ 3.1428 × 100 - 3.14 × 36/2

Shaded region→ 314.28 - 3.1428 × 18

Shaded region→ 314.28 - 56.570

Shaded region→ 257. 709

Hence,

Area of shaded region = 257. 709 sq.cm
