Answer:
3
Step-by-step explanation:
The circle gets bigger, so the only option is a positive whole number.
find the area of the base which is 8*8=64 in^2
then the triangles one is 2*[(6*4)/2)]= 24 in^2 and theres 4 of them so times 4
24*4=96 in^2
then add and u get 160 in^2
90^2-54^2=5184
root 5184=72
pr=72
