Answer:
6.81m
Step-by-step explanation:
Using the formula for finding the length of am arc
L = theta/360° × 2πr
theta is the angle subtended by the drum in rotation
r is the radius of the drum
Given theta = 315.7°
r = 1.1m
Substituting the given values into the formula we have:
L = 315.7/360 × 2π(1.1)
L = 315.7/360 × 2.2π
L = 315.7/360 × 2.2(3.14)
L = 315.7/360 × 6.91
L = 6.81metres
Line of about 6.81metres will be wounded around the drum
You would square 3968 and subtract 1.
Answer:
x=5, y=-3
Step-by-step explanation:
we can find the answer by plugging in x=3y+14 to the second equation
5(3y+14)-2y=31
simplify
15y+70-2y=31
13y=-39
y=-3
now, plug in this to the initial equation x=3y+14
x=3(-3)+14
x=-9+14
x=5

Step-by-step explanation:
You've been working with rectangular prisms all night, and the same formula gives the volume of every one of them. Unfortunately, you used way more time asking other people for answers than it would take you to solve them on your own.
The formula is:
Volume = (length) times (width) times (height) .
With that formula, you can directly solve problems #1, #2, #3,
#4, and #8. It's also the only math you really need to solve #9 ...
but you also need to use your brain cells for #9.
For #6, start with the same formula:
Volume = (length) x (width) x (height)
Divide each side by
(width) x (height), and
then it says: Length = (volume) / (width x height) .
#6 gives you the volume, width and height.
You can just write them into this equation,
and bada-bing, you'll have the missing length.
