1. Area: pi x r^2
Radius: 6.9m
Area: 3.14 x 6.9^2
Area: 149.5m
2. Area: pi x r^2
Radius: 150ft
Area: 3.14 x 150^2
Area: 70,650ft
3. Area: pi x r^2
Radius: 8in
Area: 3.14 x 8^2
Area: 200.96in
Area: pi x r^2
Radius: 2in
Area: 3.14 x 2^2
Area: 12.56in
200.96/12.56 = 16
Therefore, it will take 16 4 inch diameter cookies to equal the area of one giant cookie.
