Answer:
8π
Step-by-step explanation:
If we are given the diameter of this circular fence, then we can solve for the radius. Just take the diameter of 4 and divide by 2 which is 2.
The circumference of a circle is 2πr²
Just plug in the variables and you get 2π(2)² which is 8π
Hope this helps! :)
Since all the options are in the slope intercept form, we find the equation using the formula,
We can find m, the slope using the formula,
On substitution,
We use any of the points, say (-2,-3) to determine the value of c.
The equation is therefore,
The correct answer is D.
We are given equations y =3.5x and y=25x +40.50.
Where x represent time in hours and y represents cost in dollars.
We need to determine that which equation is not the equation of a proportional relationship?
In first equation we have slope 3.5 and y-intercept 0.
In second equation, we have slope 25 and y-intercept 40.50.
<em>In order to have a a proportional relationship, there should be y-intercept =0.</em>
<h3>Therefore, y= 25x + 40.50 is not the equation of a proportional relationship.</h3>
Che set amount by A+ Fence company would be around $140 per foot
A: l x w = a formula for area
l = w + 48 length
w(w+48) = 3024 substitute l with w+48
w^2 + 48w -3024=0 —solution to part A
B: w^2 + 48w - 3024 = 0 factor
(w-36)(w+84) = 0
Solutions for width = 36,-84
A width can’t be negative, so the width is 36 inches
