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.

Find the number of tiles in the 57th figure. justify your answer using an algebraic expression
attashe74 [19]
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!!

Mark is going to an awards dinner and wants to dress appropriately. He is running behind schedule and asks his little brother to
Cerrena [4.2K]

Answer:

The answer is "\bold{\frac{2}{3}}".

Step-by-step explanation:

Pick a shirt first: 3 choices

Pick slacks next: 2 choices

Then choose a tie: 1 choice

Total: 3 \times 2 \times 1 = 6 outfits.

These will be similarly divided between the two slacks, so 3 black slack outfits of 6 = \frac{1}{2}.  Similarly, the 6 styles are also divided between the option of 3 shirts. 2 blue shirt outfits 6 = \frac{1}{3}

To recognize that over outfits are a mix of a blue shirt and black slack, it would be twice many more to add \frac{1}{2} \ and \ \frac{1}{3}. Add \frac{1}{2} \ and \ \frac{1}{3}, and remove the chance for both the black slack shirt and outfit and are one of the six outfits:

\to \frac{1}{2} + \frac{1}{3} -\frac{1}{6} =\frac{3+2-1}{6}  =\frac{4}{6} = \frac{2}{3}
