Hey there,
The equation for the volume of a cylinder is V = πr²h.
The first step into finding the radius is to plug in what you already know into the equation:
We divide both sides by 5:
Now we divide both sides by π:
Finally we just do the square root of 49.0197224723:
The radius therefore would be about 7cm.
Hope I helped,

Answer:
Each knight will guard <u>288 minutes</u> in one day.
Step-by-step explanation:
Given:
A castle has to be guarded 24 hours a day. Five knights are ordered to split each day's guard duty equally.
Now, to find the minutes will each night spend on guard duty in one day.
As, in 1 hour there are 60 minutes.
Thus, in 24 hour there are 60 × 24 = 1440 minutes.
Total minutes for guarding = 1440 minutes.
So, there are knights ordered for guarding are = 5.
And each day's guard duty equally.
Now, to get the minutes will each night spend on guard duty in one day we divide the total minutes for guarding by number of knights that is 5:


Therefore, each knight will guard 288 minutes in one day.
Answer:
15 degrees.
Step-by-step explanation:
- 5x + x + 90 = 180.
- 6x + 90 = 180.
- 6x = 90.
- x = 15.
These are all of the steps to completely get the correct answer to this question.
Hope this helps!!!

Determine the radius of the circle
First, we have to determine the center of the circle;
Since the circle has its center on the x axis; the coordinates of the center is;

Next is to determine the value of x through the formula of radius;

Considering the given points



Substitute values for
in the above formula
We have:

Evaluate the brackets


Eva;uate all squares


Take square of both sides
Evaluate the brackets



Collect Like Terms


Divide both sides by 2

This implies the the center of the circle is

Substitute 0 for x

Substitute 0 for x and y in any of the radius formula


Considering that we used x1 and y1;
In this case we have that; 
Substitute -3 for x1 and 2 for y1
