I'm sure the answer is range: 0,4
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
The formula for the circumference is 2πr.
Radius is half of the diameter which comes out to be 13.
2 x π x 13 = 81.6
Hope this helps!
