Translate the English phrase into an algebraic expression: the sum of 13x and 3x.

13x+3x is the translation for the English phrase "the sum of 13x and 3x).

Step-by-step explanation:

Here, the sum of 13x and 3x means to add so we have to put an addition sign between both numbers. Sorry if you don't understand... my explanation is pretty off but my answer is 100% correct: D

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 !
