Answer:
The amount of paper needed = 363.3 in²
Total amount of paper and plastic needed = 564.3 in
Step-by-step explanation:
As the diagram isn't given.
Consider a right cone shown in the ATTACHMENT.
where
r = 8 in
h = 12 in
First find the value of hypotenuse s by using Pythagoras theorem
<h3>Find Lateral Area:</h3>The amount of paper needed to cover the candle is lateral area, which is given by:
Total amount of paper and plastic is the surface area:
Answer:
<h2>C(V(r)) = 3.2πr3</h2>Step-by-step explanation:
This problem is a composition of function defined by C(V(r)), now we have the functions and
, where the first depends on the radius, and the second dependes on the volume, that means, to find the number of ounce of coffe, we need to determine the volume of the cylinder, that's why we have to replace the volume function inside the ounces function,
Therefore, the right answer is the last choice.
Answer:
The answer is 1/9 ⇒ the second answer
Step-by-step explanation:
* In the exponential functions we have some rules
(1) b^(-m) = 1/(b^m) (for all nonzero real numbers b)
- If we have negative power we reciprocal the base
to get positive power
(2) (b^m)^n = b^(mn)
- If we have power over power we multiply them
* In our problem:
- At first change 27 to b^n
∵ 27 = 3 × 3 × 3 = 3³
∴
* Lets use rule (2)
∴ ⇒ 3 × -2/3 = -2
* Use rule (1)
∴ ⇒ reciprocal the fraction to change the sig of the power
* The answer is 1/9
