5/2 minus something equals 1/3

13/6

Step-by-step explanation:

Got to put the denominators equal, so find the LCD or lowest common denominator, which in this case is 6

15/6 minus blank equals 2/6

subtract 15/6 minus 2/6 and you get

13/6

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 !
