d = diameter : d =19 \ ft \\ \\radius : r=\frac{d}{2}=\frac{19}{2}=9.5 \ ft \\\\ length of object : \ h=210 \ ft \\\\Circle Area : \ A= \pi r^2\\ \\Circular Volume = A*h = \pi r^2h \\ \\Circular Volume = \pi\cdot 9,5^2*210 =90,25 \cdot 210\cdot \pi =18952.5 \ \pi \ ft^3

4-58. Lisa plans to retire on her 61st birthday. On her
mojhsa [17]

Answer:

Lisa invest "$2180.81" in her bank.

Step-by-step explanation:

The given values are:

On Lisa's 62nd birthday,

she withdraw = $10,000

The annuity of $A will remain at 3 percent for 40 years. The retirement pension of $10000 lasts 23 years at rate percentage of 3 but begins 40 years later.

⇒  A\times (\frac{P}{A} ,3 \ percent,40) - 10000 (\frac{P}{A} ,3 \ percent,23)\times \frac{1}{(1.03)40} = 0

⇒  A\times 23.1148 - 10000\times 16.4436\times 0.3066 = 0

⇒  A = 10000\times 16.4436\times \frac{0.3066}{23.1148}

⇒      = 10000\times 16.4436\times 0.0132

⇒      =2180.81 ($)

so basically what you would have to do is set up your numbers. it would look something like this. 68

                                    × 49

                                 -------------

and would then multiply 9 by 8, 9 by 6. put it down below the line while making sure to carry the numbers if need be. then do the same with the 4 times 8, and 4 by 6.
