Question

Find the volume use pi as part of the equation round to nearest hundred

Answer 1

340.17 ft.

Explanation:

Using the formula, πr²h ÷ 3 (3.14 × radius × radius × height ÷ 3), we can plug-in the unknown values.

'r' means radius; 'h' means height; 'π' means pi.

The radius is 5; the height is 13.

πr²h (3.14 × radius × radius × height ÷ 3) - π5² × 13 = 340.166666667 (3.14 × 5 × 5 × 13 ÷ 3 = 340.166666667)

340.166666667 ≈ 340.17

Therefore, the area of this circular cone is 340.17 ft.

Answer 2

V = 340.339

Explanation:

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

V =
`\pi`
`(5)^(2)`
`(13)/(3)` = 25
`\pi`
`(13)/(3)` = about 340.3392 = 340.339
