Pi is an irrational number meaning it has no end, 3.14 is just an estimate which means that it is not accurate.
I hope this helps you
volume of cylinder =pi.r^2.h
volume =3,14×6^2×15
volume = 1695,6
1695,6÷15=113,04
25/100 also 1/4
they are the same fraction, one of them is just simplified
I=prt.
I= $200 X 4% X 7.
I= 8 X 7.
I= 56. Her total interest earned was $56 :)
