2.A
3.C

5.A
6.A
7.A
You gotta post the full answers, not just the letter answers.
We all have different answers, so some of us will fail and some of us won’t.
I will probably come back with the answers for everyone! 😀😌
surface areas of similar solids are proportional to the square of their corresponding sides
area of larger/90 = 10^2/5^2
area of larger = 90(100/25) = 360 in^2
You were incorrect on all you made me fail
since I've used this platform this semester to generally check my answers, here's a pretty late contribution
1 - 803.8 cm2
2 - 452.2 m2
3 - 267.9 ft3
4 - 2 cm
5 - 12 mm
(I got these last 2 wrong, I don't see how I'm wrong but here's what its telling me the answers are)
6 - 360 in2
7 - 120 ft3
*** MY PERSONAL ANSWERS FOR THESE, DONT ENTER THEM
*6 - 180 in2 (incorrect)
*7 - 120 ft3 (incorrect)
if somebody understands these, please explain them to me, im tired and this is my last day working of the semester, so if any of these are incorrect now, tag me and please fix them, thanks.
