Step-by-step explanation:
Do you see a pattern? Each time it decreased by 3. 33-3=30, 30-3=27, the pattern goes on, just do the same with the last shown number. 21-3=18
Answer:
25
Step-by-step explanation:
To calculate rate, divide the number of cans by the time to get "Cans per minute".
300/15min = 20/min
Let m represent minutes and c for cans.
We write an equation for the problem:
c = 20m
We want to know the time for 500 cans, so substitute 500 for c.
500 = 20m
Isolate m and solve:
m = 500/20
m = 25
It will take 25 minutes to put 500 labels.
V=(1/3)hπr^2 where h=height and r=radius
given
radius=3
height=2a
r=3
h=2a
v=(1/3)hπr^2
v=(1/3)(2a)π(3)^2
v=(1/3)2aπ9
v=6aπ
so the expression would be some variaant of v=6aπ
