Answer:
418.00 cm³
Step-by-step explanation:
The volume of a cylinder is given by πr²h (r being the radius and h being the height)
The radius is half of the diameter: 6.4/2 is 3.2.
The height shown here is 13.
Instead of pi, the question says to use 3.14 instead of pi.
Putting these all together, you get 3.14×(3.2)²×13.
This can be expanded to 3.14×10.24×13.
From there, multiplying it all together gives you 417.9968 cm³.
The problem says to the nearest hundredth, so you want to round it to 2 decimal places. Since the 6 is above 5, it gets rounded up, leaving you with 418.00 cm³.
Answer:
14 days
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
25n+100=450
Step 2: Subtract 100 from both sides.
25n+100−100=450−100
25n=350
Step 3: Divide both sides by 25.
25n/25 =350/25
n=14
Answer: There were 6 guides on Sunday.
Step-by-step explanation:
I suppose that this is a question about equivalent ratios:
It is said that the company had the same ratio of tourists to guides on Saturday and Sunday.
RATIO OF TOURISTS TO GUIDES:
SATURDAY: 120 : 18
SUNDAY: 40 : ?
Divide 120 by 40:
120/40 = 3
Divide 18 by 3:
18/3 = 6
Therefore:
SAT: 120 : 18
SUN: 40 : 6
Check it by multiplying both numbers in the ratio 40 : 6 by 3:
40 • 3 : 6 • 3
= 120 : 18
(You get the ratio from Saturday)
Hope this helps!
