Which inequality can represent the following: " x is at most 30"

x ≤ 30

Step-by-step explanation:

≤ is less than or equal to which means it is less than or is 30 but no greater than 30 hence the "at most"

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 !
