Am I to assume this is for volume? The volume formula for a cylinder...oblique or not...is V = 1/3pi r^2 h. Cavalieri's principle tells us that the formulas for both are the same. So V = 1/3*pi*100*11 and V = 366.67 pi
You can use the proportion.
$4.99 / 1 kg = x / 1.8 kg
x = ($4.99 * 1.8 kg) / 1 kg
x = $8.98
Therefore, in 1.8 kg of potatoes, it costs at $8.98

Answer:
B
Step-by-step explanation:
We are given that <em>x</em> and <em>y</em> are functions of time <em>t</em> such that <em>x</em> and <em>y</em> is a constant. So, we can write the following equation:

The rate of change of <em>x</em> and the rate of change of <em>y</em> with respect to time <em>t</em> is simply dx/dt and dy/dt, respectively. So, we will differentiate both sides with respect to <em>t: </em>
<em />
<em />
Remember that the derivative of a constant is always 0. Therefore:

And by subtracting dy/dt from both sides, we acquire:

Hence, our answer is B.
Answer:
$3787.5
Step-by-step explanation:
Given data
Cost price= $25,000
Rate of decrease= 7%
Time= 2020-2026= 26 years
Let us apply the formula
A= P(1-r)^t
substitute
A= 25000(1-0.07)^26
A=25000(0.93)^26
A= 25000*0.1515
A= $3787.5
Hence the worth will be $3787.5
