Help!! For this question I got 254.34 as my final answer but when I checked my answer it told me I was wrong?

a = 254.5 mm² ( if using accurate value of π)

a = 254.4 mm² (if using 3.14 as approximate value of π)

Step-by-step explanation:

a = πr²

a = π * 9²

a = π * 81

(note using π = 3.1415926536)

a = 254.4690049408

Rounded

a = 254.5 mm²

(a = 254.4 If using π = 3.14)

rodrigo is subject to a framing bias i believe.
