Question

What is the volume of a cone with a radius of 2 and a height of 19?

Answer 1

i looked it up its V≈79.59

Explanation:

Answer 2

Remember that the cone volume formula is
`V=\pi r^2(h)/(3)` , with r = radius and h = height. Using our information, we can form our equation as such:
`V=\pi 2^2(19)/(3)` (I'll be keeping the answer in pi form.)

Firstly, solve the exponents:
`V=\pi 4(19)/(3)`

Next, multiply 4 and 19/3 together and your answer should be (rounded to the hundreths): V = 25.33π un^3
