Because this scale factor is smaller than 1, which means it’s making it smaller than the original.
1st option, <
sqroot of 7 is 2.6, 14/5 is 2.8.
2.8 is bigger than 2.6
So if 18 plus 1/4 of the number is the number the means 18 is 3/4 of the number so 18 divided by 3 is 6 so 1/4 = 6 now add 6 to 18 to get 4/4 of the number which is 24 number = 24
Your answer is the 3rd option.

You must divide by π on both sides, therefore d=c/π
