Which of the following uses the correct formula to find the approximate circumference of a circle that has a radius of 450?
C≈3.14⋅150
C≈2⋅3.14⋅450
C≈3.14⋅450^2
C≈3.14⋅450÷2
Please answer this correctly. Thank you.
C≈2⋅3.14⋅450
To find the approximate circumference of a circle with a given radius, we use the formula:
C = 2 * π * r
where C represents the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
Out of the four options provided, the correct formula to find the approximate circumference of a circle with a radius of 450 is:
C ≈ 2 * 3.14 * 450
So, the correct option is:
C ≈ 2 * 3.14 * 450
