Answer:
A)
A = 0 B = 2π
C = 0 D = 2
E = - 2 F = 5
B)
V = 216 π
Step-by-step explanation:
Using cylindrical coordinates
x= rcosθ , y = rsinθ, z = z
Then, dV =rdzdrdθ
where x² + y² + z² = r² + z²
E= ( 0 ≤ θ ≤ 2π, 0 ≤ r ≤ 2, -2 ≤ z ≤ 5 )
∴
V = 12π (4 + 14)
V = 12π(18)
Answer: y=-9/8x+7
16.92
5.64 x 3 = 16.92
