The unit of measure that would be appropriate to measure a bathtub is A. Liters.
Answer:
4pi in^2
Step-by-step explanation:
Lateral surface area of a cylinder = 2πrh
π = pi
r = radius
h = height
Let me illustrate with an example
A cylinder has the following dimensions
r = radius = 20
h = height = 10
lateral area = 2 x π x 20 x 10 = 400π
If dimensions are reduced to one-fifth their original length, new dimensions are
r = radius = 20 x 1/5 = 4
h = height = 10 x 1/5 = 2
New lateral area = 2 x 4 x 2 x π = 16π
change in lateral area = 400π / 16π = 25
If dimensions are reduced by 1/5, lateral area would reduce by 25
100 pi / 25 = 4
<span>Lines r and s are parallel; so they have same slope
</span><span>If the slope of line r is 2/5 then slope of line s would be 2/5

Answer: 371697
Step-by-step explanation:
For continuously compounded values, we use the formula Pe^rt, or Pert. P is our principal/initial value, 230000. e is the constant e, r is our rate, 4% or .04, t is our time, 12. So, 230000*e^(.04*12)=371697.112504, rounding down, 371697.
1/4 of 12 simply means that if there are 4 equal quarters in 12, how many would be in each of those quarters, or 1/4*12 or 12/4. 12 divided by 4 means that the 12 is on the top and 4 is on the bottom, meaning 12/4.
