Answer:
Step-by-step explanation:
First off you need to identify the relationship between the 2 widths. The answer to that is 3 feet in real life = 15 inches in scale drawing. This means multiply by 5 and convert feet to inches. All you need to do is apply this to the height. We have 5 feet, if we multiply by 5 we get 25. Then remember it needs to be inches, so the answer is 25 inches.
We know, Volume of a Cylinder = πr²h
Here, r = 2/2 = 1 ft
h = 3 ft
Substitute their values,
v = 3.14 * (1)² * 3
v = 9.42 ft³
In short, Your Answer would be: 9.42 Ft³
Hope this helps!
This will be 18.39, 6 is higher than 5, so the 8 is going higher so it's a 9 and you will get 18.39
Answer:
37 dimes and 10 nickels
Step-by-step explanation:
let d = # dimes
let n = # nickels
we can set up a system of equations:
n + d = 47
.05n + .10d = 4.2
if we solve the first equation for 'n' we get:
n = 47-d
now we can substitute this in for 'n' in the second equation:
.05(47-d) + .10d = 4.2
2.35 - .05d + .10d = 4.2
2.35 + .05d = 4.2
subtract 2.35 from each side to get:
.05d = 1.85
d = 1.85÷.05
d = 37
if d+n = 47 and d=37 then n = 10
Check:
.05(10) + .1(37) should equal 4.2
.50 + 3.7 = 4.2 [It Checks Out]
