C≈3.14⋅450÷2
upper C approximately equals 3.14 times 450 divided by 2

C≈3.14⋅4502
upper C approximately equals 3.14 times 450 squared

C≈3.14⋅150
upper C approximately equals 3.14 times 150

C≈2⋅3.14⋅450

Answer 1

C≈2⋅3.14⋅450

Answer 2

why

Answer 3

The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. In this case, the radius is 450, so the correct formula would be C ≈ 2π(450) = 2(3.14)(450) = 2826. This is why the correct formula is C ≈ 2⋅3.14⋅450.
