Is 4: 9 equivalent to36: 72 use a tape diagram to find the answer

I'm not sure what you mean by "tape diagram" but you can use a proportion to check. Assume that 4/9 is equal to 36/72 for now. We'll use cross multiplication to show that it's actually false.

4/9 = 36/72

4*72 = 9*36 ... cross multiply

288 = 324 ... this is false

The last equation is false because we get two different values on either side, so the first equation must be false

So 4:9 is not the same as 36:72

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 !
