Answer:
length = 100 m
width = 63.66 m
Step-by-step explanation:
Let's call
x: lenght of rectangle
y: width of rectangle, and also diameter of the semicircles
Perimeter: 2*x + π*y = 400
or:
x = 200 - π/2*y
Area of the rectangle = x*y
Replacing:
A = (200 - π/2*y)*y
A = 200*y - π/2*y²
At the maximum:
dA/dy = 200 - π*y = 0
y = 200/π
y = 63.66 m
and
x = 200 - π/2*63.66
x = 100 m
Answer:
0.8
I hope this helped, have a great day!
Answer:
70%
Step-by-step explanation:
there is 10 and 7 of them are filled which is 7/10 since we are dealing with percentages we need the bottom to be 100 so 70/100 or 70%
