You run 3 miles up a hill and 3 miles down the hill. You run 25% faster going down the hill than up the hill. Let r be your speed (in miles per hour) while running up hill. Write an expression that represents the amount of time you spend running on the hill.​

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 !

it could be 1,3 and more others to create a cylinder.

step-by-step explanation:

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
