Each group will have the same number of boys and girls in a group. Find common factors for the number of boys and girls.
6th grade :
64 girls = 8 * 8
72 boys = 8 * 9
There will be 8 groups consisting of 8 girls and 9 boys
7th grade :
81 girls = 9 * 9
63 boys = 9 * 7
There will be 9 groups consisting of 9 girls and 7 boys

60 boys = 4 * 12
There will be 4 groups consisting of 17 girls and 12 boys
The area of the circle would be 16pi
