Heinrich is a vacuum cleaner salesman. For each vacuum cleaner he sells, he receives $7. If he sells between 30 and 40 vacuum cleaners a month, about how much will he earn in a month?

Hi! This is just a simple multiplication problem!

So he recieves 7 dollars for each vacuum cleaner therefore we must multiply 7 by the amount he sells.

7*30 =210

7*35=245

7*40 280

That means he will earn somewhere between 210 dollars - 280 dollars

Hope this helped!

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 !
