Answer 1

Answer: 452.16

Step-by-step explanation: The formula for area is A=πr². The radius is half of the diameter, which would give us 12. so just plug in. 12² is 144. 144π is 452.38. (Which is close to 452.16) Hope this helps :)

Answer 2

452.16. the diameter is 24 so the area has to be ~452.16
