50.24
Explanation:
4^2
4x4=16
16x 3.14= 50.24
Note the equal sign. What you do to one side, you do to the other. Isolate the p. Do the opposite of PEMDAS.
first, subtract 5r from both sides
2p + 5r (-5r) = q (-5r)
2p = q - 5r
Next, divide 2 from both sides
(2p)/2 = (q - 5r)/2
p = (q/2) - (2.5r) is your answer
hope this helps

Step-by-step explanation:
We are given that
Side of square shaped piece= 3ft
Let square of side x cut from each corner of square piece cardboard.
Length of box=
Breadth of box=
Height of box= x
We have to find the largest volume of box.
Volume of box is given by
Differentiate w.r.t x
Substitute
Again differentiate w.r.t x
Substitute
Substitute
Therefore, at
Hence, the volume is maximum at
Substitute the value then we get
