Step-by-step explanation:
The ratio is 459/484.
The percent is:
459/484 × 100%
= 94.83%
The percent left is:
100% − 94.83%
= 5.17%
First you find the area of the square which is 8²=64 than you find the area of a circle using the formula πr² you get 201.06 and divide it by 4 because you only need the quarter and you get 50.26 the last step is to add the two areas together and you get 64+50.26=114.2
