Answer:
100rz cents.
Step-by-step explanation:
The price of cement with respect to its weight is proportional.
So, we can write p ∝ w
where p is the price in dollars and w is the weight of the cement in pounds.
⇒ p = kw ............... (1) {Where, k = proportionality constant}
Given that, one pound of cement cost r dollars.
So, from equation (1), we can write
r = k(1)
⇒ k = r
So, the equation becomes p = rw .............. (2)
Now, for w = z pounds, the price will be p = rz dollars. {From equation (2)}
Therefore, the price of z pounds in cents will be 100rz cents. (Answer)
Meg would be a to be correct
The volume of a cylinder is given by

where
is the base area, and
is the height.
We are already given the height, which is 10.
We can deduce the base area since we are given a diameter: the radius is half the diameter, so it's 8, and the area of a circle is given by

So, the volume is
