Answer:
False
Step-by-step explanation:
The volume of a right cylinder is given by the formula:

And the volume if a oblique cylinder is <em>also</em> given by the formula:

Regardless of the height, if the radius are different, then the volume would not be the same.
Algebraically:

What?
i dont know maybe...hmmmm
Let the total amount that Sarah deposited be $x
using the annuity formula:
A=P[((1+r)^n-1)/r]
A=future value
r=rate
n=number of years
from the information given:
A=$500000
r=2.75%
n=65-42=23 years
p=$x
thus plugging our values in the formula we get:
500000=x[((1+0.0275)^(23)-1)/(0.0275)]
500000=31.50x
x=15,872.04883
She deposited 15,873.04883 per year
The monthly deposit will therefore be:
15873.04883/12=$1322.67
