The circumference formula is 2 times pi times radius. In this case, we are substituting pi with 3.14. So, 3.14 times 2 times 4 (the radius) = 25.12. Therefore, the circumference is 25.12 m.

The formula for the area of a circle is pi times radius squared.

4^2 = 16.

16 times 3.14 = 50.24

So, the area of the circle is 50.24 squared, or 50.24^2.

the density of pure gold 1,204 pounds per cubic foot? how many cubic feet is 481.6lbs of pure gold?

Answer:

Volume of Gold = 0.4 cubic feet.

Step-by-step explanation:

First we have to make sure the units are same as the units the answer is required in.

Answer should be given in cubic feet.

Density is given in pounds per cubic foot. And Mass is given in pounds. So units are in order. Therefore, we can go ahead with the calculation.

The Density of Gold = [Mass of Gold/Volume of Gold]

By substituting values,

$1204$ ponds per cubic foot = [ $481.6$ pounds / Volume of gold]
