Ответ:
1: 78.5
2: 7,850
1: we know the radius is 5, so we put it in the expression, making 3.14x5 to the second power, which makes 25 ( because 5x5) so 3.14x25=78.5
so our area is 78.5m
2:our radius is 50, so when we put it in the expression 3.14x50 to the second power we get 2500, so agian we do 3.14x2500=7850
so our area is 7850mm
