There is a formula for finding the number of faces, edges, and vertices of any convex polyhedron. So if you don't know the shape you can use the formula.
V + F - E = 2
12 + F - 18 = 2
F - 6 = 2
add 6 to both sides
F = 8
CHECK:12 + 8 - 18 ??=?? 2
20 - 18 = 2 checks

Answer:
19 (using "3.14" as pi)
18.99036781...(using pi button)
Step-by-step explanation:
Formula: C=dπ
so, (59.66)=dπ
you would divide circumference (C) by pi which will get you the answers above :)
hope this helped
7^6 = 117,649
7 x 7 x 7 x 7 x 7 x 7 = 117,649
