I think this is how you solve this
So the answer to this question is:
A= bees: f(t) = 1500 × (0.88)∧t
plants: g(t) = 800 - 25×t
B: (Bees) 1500 × (0.88)∧6= 696.60
After 6 months (696 bees ):
800 - 25×6 = 650 (Flowering Plants)
After 6 months:
650 flowering plants
C: 1500 × (0.88)∧t=800 - 25×t
t = 6.779965672
Answer is it will take 7 months or 6 for the bees and the plants.
Hope this helps!
Refer to the diagram shown below.
In spherical coordinates,
r² = x² + y² + z²
x = r sinφ cos θ
y = r sinφ sin θ
z = r cosφ
The element of volume is
dV = r² sinφ dr dθ dφ
Therefore, for the sphere with radius = 3,
The integration yields
Answer: 1250π
