Which of the following uses the correct formula to find the approximate circumference of a circle that has a radius of 12? Use 3.14 for π and express your answer to the hundredths place.
18.84
75.36
452.16
37.68
The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle.
Substituting r = 12 and using 3.14 for π, we get:
C = 2(3.14)(12) = 75.36
Therefore, the correct answer is 75.36, expressed to the hundredths place.
To find the approximate circumference of a circle, you can use the formula C = 2πr, where C is the circumference and r is the radius.
In this case, the radius of the circle is given as 12. So, we can substitute the value of the radius into the formula: C = 2π(12).
Now, let's evaluate the formula using the value of π as 3.14: C = 2(3.14)(12) = 75.36.
Therefore, the correct answer is 75.36.
The correct formula to find the approximate circumference of a circle is C = 2πr, where C represents the circumference and r represents the radius.
Using this formula with a radius of 12 and a value of 3.14 for π, we can substitute these values into the equation:
C = 2 * 3.14 * 12
C ≈ 75.36
Therefore, the correct answer is 75.36.
