Answer:
803.84=A
Step-by-step explanation:
The area of a circle can be found by using the equation 
=A.
=A
=A
(3.14)(256)=A
803.84=A and the units are, how ever the radius is measured cubed
It is A!!!!!!!! :) lmk if it’s not correct please!
I’m assuming that you only need the answer to the last one but let me know if I’m wrong :)))
I believe C would be 23.6
<span>We let x be the length and y be the width of the rectangle. Then,
Perimeter = 2x + 2y
100 = 2x + 2y
50 = x + y
y = 50 - x
Area = xy
A = x(50 - x)
A = 50x - x^2
We then take the derivative; set it equal to zero:
A ' = 50 - 2x
0 = 50 - 2x
2x = 50
x = 25
y = 50 - x
y = 50 - 25
y = 25
Therefore, the dimensions are 25 and 25.</span>
