Answer:
volume of xy-plane outside the cone = 16π/3
Step-by-step explanation:
using cylindrical coordinates
z² = x² +y² =====>z²=r²=====>z=r
x² + y² =4 ====>r = 2
So, the volume ∫∫∫dV equal
∫(θ = 0 to 2π) ∫(r = 0 to 2) ∫z=0 to r) 1 x (r dz dr dθ) via cylindrical coordinates
= ∫(θ = 0 to 2π) ∫(r = 0 to 2) r² dr dθ
= ∫(θ = 0 to 2π) (1/3)r³ {for r = 0 to 2} dθ
= 2π x 8/3
= 16π/3
(1 + x) (13) = 13+6.5
13x + 13 = 19.5
13x = 6.5
x = 0.5

Answer: Choice B) The probability of buying a taco OR a drink is 45%
The uppercase P means "probability". Using parenthesis with the P tells us "probability of whatever event happens"
P(A) means Probability of event A happening
P(B) means probability of event B happening
P(A or B) means Probability of event A or event B (or both) happening
You then replace A with "customer buys taco" and B with "customer buys drink" to get the answer mentioned above.
I think it’s B good luck if I am right please mark brainliest
