Answer:
7/8 miles
Step-by-step explanation:
Given data
From her house to the park= 1/4 miles
Around the park = 3/8 miles
back home= 1/4 miles
Total distance= 1/4+3/8+1/4
LCM= 8
=2+3+2/8
=7/8 miles
The area ratio is 1:16 meaning that the old area is 1 while the new area is 16. So this is another way of saying "the area is multiplied by 16"
Take the square root of each part of the ratio of 1:16 and we get 1:4
So this is the scale factor. It tells us how the linear components of the circles relate to one another. If the circumference of the smaller circle is 1,then the larger circle has a circumference of 4.
Therefore, the circumference has been multiplied by 4
30000 is the answer I think
