Respuesta :
Answer: 14π in
Step-by-step explanation:
Formula for circumference:
2πr
Plug in your values:
(2)(7)π = 14π in
Correct Answer: 7π
Explanation: Formular for circumference is 2πr. Since the diameter of the circle is 7 inches and you need the radius, you have to divide the 7 by 2. Once you have the radius, plug it in to the formula.
r = 7/2 = 3.5
(2)(3.5)π
= 7π
