Question

The circled one is what I need help with, thank you :)

Answer 1

We’re talking about this too Rn- I hate geometry

Answer 2

you have to first do pythagorean theorem. 1.25 squared (1.25 came from dividing 2.5 by 2) plus x squared = 4 squared. once you find x, use volume formula which is v= 1/3 base times height (: hope this helped!!!
