Let the length of the square base be x inches .
And the height of the box be y inch .
Volume = x*x*y
4000 = x *x *y

S = x*x + 2xy + 2 x y




S ' =0



x = 20

The answer is 36
Answer - 36
Answer:
the answer is acute 35.
Step-by-step explanation:
Answer: 12πins.
Step-by-step explanation:
Since the area if a circle = πr²
From the question
Area of the circle = 36πins²
To find the circumference of the circle, we need to find the common radius of the circle and this could be achieved from the area of the circle given above.
πr² = 36π, solving this gives. Divide through by π
r² = 36
r = +/-√36
= +/-6
Now to find the circumference of the circle, we substitute for r in the formula below.
Circumstances = 2πr
= 2 ×π × 6
= 12πins.
