In the equation for surface area the radius is squared ( r^2)
If the radius is doubled, the radius would be 2^2 more which equals 4
The surface area would be 4 times the old surface area.
Answer:
60°
Step-by-step explanation:
90° = 6x
15° = x
60° = 4x
Answer:
6 inches
Step-by-step explanation:
The perimeter formula for a square is P = 4*S
P =24
s = ?
24 = 4*S Divide both sides by 4
24/4 = 4S/4
S = 6
Answer:

Step-by-step explanation:
The function that we have to study in this problem is

The domain of a function is defined as the set of all the possible values of x that the function can take.
For a square-root function, there are some limitations to the possible value of the argument in the root.
In particular, the argument of a square root must be equal or greater than zero, because the square root of a negative number is not defined.
Therefore, in this case, we have to set the following condition for the domain:

And by solving, we get

which means that the domain of this function is all real numbers equal or greater than 5.
