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

The savings in a bank account can be modeled using S = 1250e^0.45t, where t is the number of years the
morpeh [17]

Using the given exponential function, it is found that it will take 1.5 years for the  amount of savings to double from the initial amount deposited of $1250.

<h3>Exponential function:</h3>

The <em>exponential function</em> that models the savings in the bank account is given by:

S(t) = 1250e^{0.45t}

  • In which t is the time in years that the money has been in the account.

The time to double from the initial amount deposited of $1250 is t for which S(t) = 2(1250) = 2500, hence:

S(t) = 1250e^{0.45t}

2500 = 1250e^{0.45t}

e^{0.45t} = \frac{2500}{1250}

e^{0.45t} = 2

\ln{e^{0.45t}} = \ln{2}

0.45t = \ln{2}

t = \frac{\ln{2}}{0.45}

t = 1.5

It will take 1.5 years for the  amount of savings to double from the initial amount deposited of $1250.

considering the differences are even it means it has to fall in the middle. if you count from the top it is 22.5 numbers down giving you the number of miles.
I'm sure there is an easier way but this is how i would solve it. :)
