Question

Find the volume of a cone with a base radius of 4 cm and a height of 9 cm. Use the value 3.14 for , and do not do any rounding. Be sure to include the correct unit in your answer.​

Answer 1

Volume of a cone:
`v = (1)/(3)\pi {r}^(2)h`

Given values:

`r = 4cm \\ h = 9cm \\ \pi = 3.14`

Replacing for the values:
`(1)/(3)\pi {4}^(2) * 9 \\ (1)/(3) \pi16 * 9 \\ (\pi144)/(3) \\ Then, we have: \pi 48`

Final answer:
`v = 150.72`cm³

I hope this helps.
