2. Quadrilateral, rectangle, parallelogram
3. Quadrilateral, trapazoid
4. Quadrilateral
Bc. log a - log b = log (a/b) than use this formula will get
log x^2 -log x = log (x^2 /x) = log x so choice D. is right sure
hope helped
Answer:
<h2>A) 3 cm</h2>
Step-by-step explanation:
The formula of a volume of a cylinder:

r - radius
H - height
We have r = 1cm and H = 21cm. Substitute:

The formula of a cone:

r - radius
H - height
We have V = 21π cm³ and H = 7cm. Substitute:
<em>divide both sides by π</em>
<em>divide both sides by 7</em>
<em>multiply both sides by 3</em>

Step-by-step explanation:
Given
Base Dimension


Required
The base area of all containers
First, calculate the base area of 1 container.
This is calculated as:


Express as improper fraction

So, we have:


The number of containers is not given. So, I will use 'n' as the number of containers.
So, we have:


--------------------------------------------------------------------------------------------
Assume n is 3 (i.e. 3 containers)
The total area is:

last one. because we don't have equality sign and it can't be the third one
