V=π·r²·h
V=3.14(15²)=706.5
V=706.5x15=10597.5
V=10597.5
Let's recall that I = Prt
so... hmm we're assuming here, it doesn't say there, but this is for 1 year period.
ok... so... let's use two quantities for such interest, say "a" is the Interest for the Principal of 6000, and let's use "b" is the Interest for the Principal of 13000.
now, we know that, whatever the interest amount of "a" is, is 220
less than whatever "b" is.
we know what "b" is,
b = 130(r-1), and 220 less than that is just b - 220, or
130(r-1) - 220.
The answer to this is Fixed Costs
A triangle = 180°
one angle = 90°
second angle = 40°
third angle = 50°
