2. which value is a solution to the inequality? 3x − 5 < −20

so to solve this expression:

3x-5 < -20        add five to both sides

3x < -15          then divide three from both sides

x < -5

i am thinking c. sorry if im wrong .

step-by-step explanation:

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 !
