For one thing, Cal and Martha are <em>technically</em> in agreement; 0.1 and 0.10 are the exact same value. To see whether they're right, or whether Angela had it correct, let's take a look at the numbers 0.5 and 0.2.
As fractions, those two values would be

and

, or

and

when reduced. When you cut the original pizza in half, you cut it into <em>2 equal slices</em>. Cutting each of those two pieces into <em>5 equal pieces</em>, we get a total of 5 x 2 = <em>10 equal slices</em>. So, taking one of those slices at that point - as Angela did - would be taking

- or 0.1 - of the whole pizza.
So,
both Cal and Martha are correct.
We know that
[volume of the roll of pennies]=pi*r²*h
r=19.05/2-----> 9.525 mm
h=1.52 mm
[volume of the roll of pennies]=pi*(9.525)²*1.52---> 433.02 mm³----> 433 mm³
the answer is
433 mm³
Rational Numbers because it is a negative number and is also written in a fraction
