What statements
I don’t see any questions
The exponent is 7^9 i forgot what they were called i’m sorry
Volume = 1/3 * pi * r^2*h
= 1/3 + pi * 4*2 * 6
= 8pi m^3
The length of the rectangle is n-3, ok, the width is 2
the area of a rectangle is just length * width

so, if you simplify either of those, you'd end up with 2n-6.
because same/same = 1, and 1 * anything, is just anything itself.
