Answer:
2,799 square cm
Step-by-step explanation:
Volume of cone: (1/3)π(9^2)(40)=1,080π
Volume of cylinder: π(3^2)(21)=189π
1,080π - 189π = 891π = 2799.2 square cm
First of all, the easy part- 5 gallons -

is

. An ounce is equal to 128 gallons, so we have to convert 6 x 8 ounces (48) to gallons.

or 0.375 gallons.

-

=

or
3.875 gallons left.
Step-by-step explanation:
x^4+4y=8xy
=>8xy-4y=x^4
=>4y(2x-1)=x^4
=>4y=x^4/(2x-1)
differentiating both side we got
4 dy/dx={4x^3(2x-1)-2x^4}/(2x-1)^2
i.e, dy/dx=(6x^4-4x^3)/4(2x-1)^2
=(6x^4-4x^3)/(16x^2-16x+4)
