The correct question is
<span>A cylinder has a volume of 320 pi in</span>³<span>. and a height of 5". Find the radius of the cylinder</span>
we know that
[volume of a cylinder]=pi*r²*h----> r²=volume/(pi*h)
r=√[volume/(pi*h)]
volume=320*pi in³
h=5 in
so
r=√[320*pi/(pi*5)]--------> r=8 in
the answer is
8 in
<span>The minute hand of a watch is 6 inches long. How far does the tip of the minute hand go in 15 minutes? How much do you move in 25 minutes?</span>
Learn how to find the distance between two points by using the distance formula, which is an application of the Pythagorean theorem. We can rewrite the Pythagorean theorem as d=√((x_2-x_1)²+(y_2-y_1)²) to find the distance between any two points.

Answer:
The present value of K is, 
Step-by-step explanation:
Hi
First of all, we need to construct an equation system, so
Then we equalize both of them so we can find 
To solve it we can multiply 
to obtain 
, then we have 
.
This leads to a third-grade polynomial 
, after computing this expression, we find only one real root 
.
Finally, we replace it in (1) or (2), let's do it in (1)
