2 1/2

Step-by-step explanation:

First start by finding the common denominator, which in this case is 10, so once you've found out that, change them both, so multiply the numbers, and you should get 5/10 for every 2/10. After that, multiply 2/10 by 5 so you can get the rate for every minute. Then, in turn multiply the 5 by 5, and then you get 25/10. Simplify it into a mixed number, and you get 2 1/2.

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 !
