Answer:
A
Step-by-step explanation:
7π/12 lies in the second quadrant, so we expect cos(7π/12) to be negative.
Recall that

which tells us

Now,

and so

Answer:
i have made it in above picture hope it helps
Answer:
Volume = (250π√3)/3 unit³
Step-by-step explanation:
The shape is a solid sphere
Where rho = ρ
ρ ≤ 5
Where Phi = φ
φ = π/6 (lower limit)
φ = 5π/6 (upper limit)
Note 1π rad = 180°
We would apply triple integrals and spherical coordinates to solve for the volume of a solid sphere.
See attachment for details
From calculations,
The volume of the portion of solid sphere = Volume = (250π√3)/3 unit³
