Answer:
4 times larger (circumference)
Step-by-step explanation:
Basically the question is asking:
If radius of a circle becomes 4 times larger, how many times larger is the circumference of the circle?
Let take the original picture radius as "r", so the circumference would be:
[tex]C=2\pi r[/tex]
Now, if the radius is 4 times larger, the new radius is "4r", so the circumference would be:
[tex]C=2\pi r\\C = 2 \pi (4r)\\C = 8\pi r[/tex]
The number of times it is larger is found by taking the new circumference by original circumference, shown below:
[tex]\frac{8\pi r}{2\pi r}=\frac{8}{2}=4[/tex]
So, the circumference appears 4 times larger
