You need to put the equations?
Answer:
V = x(19-2x)(4-2x)
Step-by-step explanation:
We are given;
Length of flat piece of material =19 inches
Width of flat piece = 4 inches
We are told that the open box is to be made from a flat piece by cutting equal squares of length x from the corners and folding up the sides
Thus, we will now have;
length of open box = (19-2x) inches
Width of open box = (4-2x) inches
Height of box = x inches
We know that: Volume of box = length × width × height
So, plugging in the relevant values, we have;
Volume of box(V) = x(19-2x)(4-2x)
Answer:
Circumference of circle = πd = π × 16 =16 π in.
or
circumference of circle = 2πr = 2×π×8= 16 π in.
