Answer 6

So 1/2*5*?

Answer 7

I'm new to this so I'm unsure about a few things I'm sorry

Answer 8

You'll need to find the apothem by drawing a picture.

Answer 9

You can tell from the picture that a regular hexagon is made of many smaller triangles. You'll need to find the area of the triangles above and multiply by 12.

Answer 10

oh okay so I solve that now

Answer 11

Yeah. Just solve the equation of the bottom of the picture and multiply by 12. You'll get a bit less than 65, but you should be able to get to 65 by rounding to the nearest tenth.

Answer 12

oh alright, I'm sorry if i'm taking too long to respond I was working on a different question
