Question

Help me on this topic pls

Answer 1

Answer: 314 m^3

Explanation:

The volume of a cone is
`\pi *r^2*h/3`

`\pi = (3.14) *r^2 = (5^2)* h/3 = (12/3)`

Step 1. Simplify the expression.
`3.14 * 25 * 12/3`

Step 2. Simplify the expression again.
`3.14 *25*4`

Step 3. Multiply 25 and 4.
`3.14 * 100`

Step 4. Finish simplifying.
`314 .m^3`

Answer 2

Below

Explanation:

The volume of a cone is computed using the formula volume = 1/3 pi r^2 h

for this cone r = 5 m h = 12 m

Plug in the values : volume = 1/3 * 3.14 * 5^2 * 12 = 314 m^3
