I need help with a few problems.
I need help finding the area of a regular hexagon with an apothem of 19mm.
Also I need help with finding the area of a octagon with a radius of 20in.
Can someone also double check if I did these ratio right?
A similar pair of triangles the small triangle has a area of 12 cm and the large has an area of 48 cm.
Ratio of areas = 1:4
Scale factor = 4
Ratio of perimeter = 1:4
Did I do that one right?
Thanks for your help.
