Question

Martina has a circle with a diameter of 6 inches. She doubled the diameter to make a new circle. Now, Martina says that the ratio of the circle’s circumference to its diameter has also doubled. Correct her mistake

Answer 1

Answer:

her mistake is she didn't include pi which will change the number

Step-by-step explanation:

6x2=12

the diameter of the new circle is 12

12x pi or 3.14= 37.68

which is not double the diameter(12) of the circle
