Answer:
9.55 inches
Step-by-step explanation:
The diameter of a circle can be found by dividing the circumference by pi or 3.14. 30 divided by 3.14 is approximately 9.55.
C is the correct answer because that's the only answer where all the numbers (i.e. 3, -1, 2) all, when plugged into the function, equal 0. For example:
3³ - (4 × 3²) + 3 + 6 = 0
-1³ - (4 × (-1)²) + (-1) + 6 = 0
2³ - (4 × 2²) + 2 + 6 = 0
As we see, everything adds up to 0. So, C is the correct answer.
