Answer:
Step-by-step explanation:
The area of a circle is given by 
where 
is the radius of the circle. The diameter is given as 
feet, so the radius of this circle is 
feet.
Plugging in our values, we get:
.
The answer is D. In an ordered pair, the x-value, which tells you to move left or right, comes first, followed by the y-value, which tells you to move up or down.
The answer is the second image from left to right (B). Examples of direct and inverse variations are showed in the image below. :)
Answer:
8 sqrt(5)
Step-by-step explanation:
sqrt(45) + sqrt(125)
Rewriting
sqrt(9*5) + sqrt( 25 *5)
we know sqrt(ab) = sqrt(a) sqrt(b)
sqrt(9) sqrt(5) + sqrt(25) sqrt(5)
3 sqrt(5)+5 sqrt(5)
Add like terms
8 sqrt(5)
