5.641

Step-by-step explanation:

If you think about it, the formula for getting the area of a circle is:

So to rearrange and make r the subject, divide both sides of the equation by pi:

Now square root both sides to find r:

Plug the known area value in:

= 5.641

Hope this helps!

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
