pls solve this step by step for me .... pls​

Answer 1

Answer:

Step-by-step explanation:

Area of larger circle = πR²

= 3.14 X 30²

= 3.14 X 900

= 314 X9

= 2826 cm²

Area of smaller circle = πr²

= 3.14 X 18²

= 3.14 x 324

= 1017.36

So,

Area of shaded region = Area of larger circle - Area of smaller circle

= πR²  - πr²

= 2826  - 1017.36

= 1808.64 cm²
