- cos ( 1/2 x + 1/5 π ) = 0 ( and because if cos α = 0, α= π/2 + k π, k ∈ Z )
1/2 x + π/5 = π/2 + k π, k ∈ Z
1/2 x = π/2 - π/5 + k π / * 2
x = π - 2π/5 + 2 k π
x = 3/5 π + 2 k π = 0.6 π + 2 k π
Answer:
If k = 0: x 1 = 0.6 π = 3π/5
k = 1 : x 2 = 2.6 π = 13π/5

Quadratic functions are second-order equations of the form y=ax^2+bx+c. Their graphs form parabolas. The defining characteristic of a quadratic is that the acceleration of the outputs is a constant.
Well, that means that the sides and top are toutching the sphere
radius of sphere=10 so radius of cylinder=10
the height is the diameter or 20
V=hpir^2
v=20pi10^2
v=20pi100
v=2000pi
answer is D
