Answer:
11 inches
Step-by-step explanation:
The area of a circle can be found using:
We already know that the area is 380, so we can substitute 380 in for a.
380=
Now, we need to find the radius. To do this, we need to get r by itself
First, divide both sides by pi
120.95775675=r^2
Since r is being squared, we need to take the square root of both sides
10.9980796846=r
If we round to nearest whole number, our radius is 11 inches
The restriction of the expression as given in the task content is; x +y = 0.
<h3>What is the restriction of the expression?</h3>
The expression in the task content is rational;
(1-x-y)/(x+y).
On this note, the restriction to the expression is the values which render the denominator of the expression equal to 0 and consequently the expression value to undefined.
Hence, the restriction is; x+y = 0.

Answer: B
Step-by-step explanation: The answer would be B because you would add n the number and 6 then you would multiply it by 2
Answer:
B. 1 and 8
Step-by-step explanation:
The pattern in the first set of numbers is times 3, to find the next number multiply 54 by 3 to get 162.
The pattern in the second set of numbers is plus 4, to find the next number add 4 to 0 to get 4.
The pattern in the last set of numbers timed -3, to find the next number multiply -81 by -3 to get 243.
