Expression of "Eight less than half the sum of 4 and k” into symbol

Step-by-step explanation:

We're going to have to work backwards.

The sum of 4 and k is .

Half is simply that divided by 2.

Now, we'll subtract 8 from it.

Bam!

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 !
