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.
3,365 tiles! the equation is always (x+1)^2 (squared) + 1 = Y. because y is the number of tiles and the x is whatever figure you’re on. but the figures start like #1 is a 2x2 instead of a 1x1 so 57th figure would not be 57x57 but 58x58. and then add 1 because there’s always that top left corner tile! if you appreciate my answer giving it brainliest is always appreciated!!
Answer:
The answer is "
".
Step-by-step explanation:
Pick a shirt first: 3 choices
Pick slacks next: 2 choices
Then choose a tie: 1 choice
Total:
outfits.
These will be similarly divided between the two slacks, so 3 black slack outfits of
. Similarly, the 6 styles are also divided between the option of 3 shirts. 2 blue shirt outfits 
To recognize that over outfits are a mix of a blue shirt and black slack, it would be twice many more to add
. Add
, and remove the chance for both the black slack shirt and outfit and are one of the six outfits:

Answer:
274
Step-by-step explanation:
(52 + 4) * 5 - 2 + (-4)
56 * 5 - 2 + (-4)
56 * 5 - 2 - 4
280 - 2 - 4
278 - 4
274
Answer:
y = -2x+9
negative slope starts at 9 ( y intercept)
