Answer 1

Answer: 346.19cm²

Explanation:

π= 3.14

Divide 21 (the diameter) by 2 to get the radius( it 's half of the diameter). so the radius is 10.5

Area= πr²

= 3.14x10.5x10.5

= 346.185

So next round up the value you got to the nearest tenth, so when u round up to the nearest tenth you get 346.19
