Answer:
m³.
Step-by-step explanation:
The volume of a cylinder is found by calculating pi * r^2 * h.
In this case, h = 2.5, and r = 1.5.
pi * 1.5^2 * 2.5
= pi * 2.25 * 2.5
= pi * 5.625
So, the exact volume of the cylinder is m³.
Hope this helps!
Answer:
It didn't saying anything about rounding but the the dimensions in there exact form are:
and
.
Now if they said to round to the nearest hundredths the dimensions in this rounded form would be:
L=5.39 cm and W=5.19 cm
(Check your question again and see if you meant what you have)
Step-by-step explanation:
L is 5 less than twice W
L = 2W-5
Area of rectangle=L*W
Area is 28 means L*W=28.
I'm going to insert L=2W-5 into L*W=28 giving me
(2W-5)*W=28
Distribute
2W^2-5W=28
Subtract 28 on both sides
2W^2-5W-28=0
a=2
b=-5
c=-28
We are going to use the quadratic formula.
Plug in...
W needs to be positive so
And
Does L*W=28?
Let's check.
In the last step, I was able to do a quick multiplication because I was multiplying conjugates. (a+b)(a-b)=a^2-b^2.
Answer:
$79 total earnings
Step-by-step explanation:
Here, earnings = (hourly rate)(number of hours):
= ($8.30/hr)(6 hrs) + ($7.30/hr)(4 hrs), or
Total earnings = $49.80 + $29.20
" " = $79.00
