Question

Which point on the number line represents the approximate volume of a cone with a radius of 3 units and a height of 4 units? Use 3.14 for π.

Answer 1

in the simplest way the answer is 33

Answer 2

The point closest to the number 40

Explanation:

To find volume of cone:

`V=\pi r^(2) (h)/(3)`

(but in this case we will be substituting
`\pi` for it approximation: 3.14)

So our new equation is
`V= 3.14r^(2) (h)/(3)`

All right, let's get to work now.

• Following the order of operations our first step would be:
  `3^(2)` or 3x3 wich is 9
• Next step would be 3.14x9, which is 28.26
• After that we would solve
  `(4)/(3)`, which is 1.3 repeating but we can round to the nearest tenth and get 1.3
• Next we would multiply 28.26 by 1.3 which is 36.73800

We would next round to the nearest whole and our final answer is: 37
