Answer:
Area of the circle =
Step-by-step explanation:
Radius of the circle=
Area of the circle=
As,
Area of the circle is:
The Area of the circle is :
Perimeter (P) = 2L + 2w
64 = 2L + 2w
64 - 2L = 2w
32 - L = w
Area (A) = L x w
= L x (32 - L)
= 32L - L²
To find maximum area, calculate the derivative and set it equal to zero.
A' = 32 - 2L
0 = 32 - 2L
2L = 32
L = 16
Substitute L to solve for y: 32 - L = w → 32 - 16 = w → 16 = w
The maximum area will be 16 ft x 16 ft = 256 ft²
Answer:
3/400
Step-by-step explanation:
Let w represent earth's water
let f represent fresh water and let g represent ground water
Therefore, fraction of earth's water,w, that is ground water = 3/400
Answer:
48 sq ft
Step-by-step
I am pretty sure they mean what is the new area if the current area is expanded so: 100% + 50% = 150%
4 times 8 = current area = 32 sq ft
32 times 1.5 = new area = 48 sq ft
in the circumstance in which they were talking about the side lengths and not the original then it would be
8 times 1.5 = 12
4 times 1.5 = 6
6 times 12 = area = 72 sq ft
