What is the approximate volume of the cone below?

Mathematics

<h3>Answer:  Choice C</h3>

2,094 cm^3

==========================================================

Explanation:

The diameter of 20 cm divides in half to the radius r = 10 cm.

The height is h = 20 cm.

V = volume of the cone

V = (1/3)*pi*r^2*h

V = (1/3)*pi*10^2*20

V = 2,094.3951023932 is approximate

I used my calculator's stored version of pi when computing the volume

That value then rounds to 2,094 cm^3 when rounding to the nearest whole number.

Spent Withdrew, Down,Decrease all have negative values
musickatia [10]

True, all of them represent a negative number, for example:

You have $60 and you spent $10, the remaining money is:

60-10=50

Your savings are $1000 and you make a Withdrawal of $500:

1000-500=500

In other words for calculation purposes, they all have negative values
