☆☆☆☆☆A dodecahedron has 12 regular pentagonal faces, 20 vertices, and 30 edges. Three faces meet at each vertex.
False...
don't you mean 2:1 instead of 21. The answer is 4:1
4:1
Good luck with Apex :)
Volume of a sphere of radius r: V = 4pi/3 x r3 If the ratio of the radii of two spheres is 23,
then the ratio of their volumes will be 233 = 1,2167
True...
Total surface area is about 282.74 units2 (90 pi)
(Using pi = 3.14 gives the estimate 282.6)
SA = (pi 2r) x h + 2 (pi r2) = 72 pi + 2 (9 pi) = 90 pi
