Name a proper fraction that can be written as in whole number

1/1

2/2

3/3

4/4

Etc... Basically any fraction with the denominator being equal to the numerator.

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 !

tube or goog would be a great resource to with that question
