Answer:
D
Step-by-step explanation:
Calculate the circumference (C) using the formula
C = πd ← d is the diameter
Meg's circle has a diameter = 9 + 6 = 15 inches ( half a foot longer ), thus
C = π × 15 = 3.14 × 15 = 47.1 inches → D
47.1 inches (Answer D)
"A diameter that was "half a foot longer" " would be
9 inches + 6 inches = 15 inches.
The circumference of this longer necklace would then be:
C = πd, which here is
C = 3.14(15 inches) =
