Answer:
Step-by-step explanation:
A = 2πr + πrl
A - 2πr = 2πr + πrl - 2πr (subtracting both sides by 2πr)
A - 2πr = πrl
(dividing both sides with πr)
(splitting LHS)
happy to help :)
Remark
Interesting way to teach this problem. I'll see if I can make a table that answers the question as it is presented.
Now all you need do is collect the nine terms from the table and put the like ones together if there are any.
C. 4 and 6. 6*4=24, 4/6=2/3 (width is 2/3 the length).

Answer: 15
Step-by-step explanation:
Let's define the concept of inverse functions.
If we have a function h(x), such that it has an inverse, and:
h(x) = y.
Then the inverse function j(x) must meet the following:
j(y) = x.
Now, we want to calculate:
h( j(15) ).
Let's suppose that:
j(15) = A.
(Where A can be any real number).
then, by the above relation, we must have that:
h(A) = 15.
Now we can replace j(15) by A in h(j(15)):
h( j(15) ) = h( A ) = 15.
