How does the volume of a cylinder change when its diameter is tripled
cupoosta [38]
V(cylinder)= πr²h
d=2r,
d is diameter, r is radius.
When diameter is tripled, a new diameter D=3d,
new radius R=3d/2=(3*2r)/2=3r
R=3r

V(new cylinder)= πR²h = π(3r)²h=9πr²h

V(new cylinder)/V(cylinder)=9πr²h/πr²h=9

Volume new cylinder 9 times more the volume of old cylinder.

CAN SOMEONE PLS HELP ME ANYONE ITS ALMOST DUE
gizmo_the_mogwai [7]

Answer:

3x(2+n)+[7+n]

Step-by-step explanation:

The answer is kind of self-explanatory, but think of it this way.  If n=5, then the equation would be 3x(2+5)+[7+5]. First we would solve 2+5 which is 7. Then we would do 7+5 which is 12. We are now left with 3x7+5.
