Answer:
Volume of the cone =
Step-by-step explanation:
Height of the cone =
Radius of the base=
Volume of the cone is:
As,
Volume is:
Volume of the cone is :
We're given the algebraic expression 2x^2 - 2z^4 + y^2 - x^2 + z^4
By hypothesis, x = -4, y = 3 and z = 2
Let's replace each letter by its given value:
2x^2 - 2z^4 + y^2 - x^2 + z^4
2(-4)^2 - 2(2)^4 + (3)^2 - (-4)^2 + (2)^4
(2*16) - 2*16 + 9 - 16 + 16
32 - 32 + 9 - 16 + 16
9
So wrong. The correct answer is not -3, but 9.
Hope this helps! :D
1 - 1/2 - 2/4 = 0
A whole minus a half equals half minus another half (2/4) equals 0
